Isohexane in 137kg steel drums,Isohexane with CAS No and   Synonms

Why use steel drums instead of plastic drums for flammable materials?

Plastic barrels have their own advantages, especially the convenient transportation and stacking of plastic ton barrels, which are more and more widely used.
Whether plastic barrels can be used for flammable materials (such as gasoline) is known to those with some experience. But why not, and whether not at all, is still unclear to many people.

What harm will ordinary plastic barrels bring when they contain flammable liquids?

First of all, when ordinary plastic barrels are in contact and friction with the outside world, especially during the handling of movable plastic barrels, static charges are accumulated on the surface area. When the static electricity accumulates to a certain extent, brush type power generation may occur. The maximum energy of brush type discharge can reach 10mJ. If this brush type discharge is right near the barrel mouth, it may ignite the flammable steam emitted from the barrel mouth and backfire, resulting in flash explosion in the barrel;
Secondly, when filling the ordinary plastic barrel with liquid, static electricity will be brought into the barrel due to the friction between the liquid and the filling pipe wall during filling, and static electricity will accumulate in the barrel. Brush discharge may occur between the liquid and the conductor, so as to ignite the flammable vapor cloud in the barrel and cause flash explosion in the barrel.
Junyuan Petroleum Group has 200ml and 500ml sample trial packages, 20L small drums and 200L large iron drums. The iron bucket will be sealed with a waterproof cover on the basis of the metal cover to ensure that the oil will not be polluted. If customers have other product packaging requirements, our company can provide them on demand.
Where does aromatics come from?

Where does aromatics come from?

Aromatic hydrocarbon, also known as aromatic hydrocarbon or aromatic oil, refers to the hydrocarbon with benzene ring structure in the molecule. It is one of the basic products and basic raw materials of petrochemical industry, mainly including benzene, toluene, xylene, ethylbenzene, etc. It is the general name of a series of solvents composed of isomers of C9 and C10 heavy aromatics.
Where does aromatics come from?

  • 1. Extraction from coal

The light tar produced in the process of coal coking contains a lot of benzene. This is the initial method of producing benzene. The generated coal tar and gas are passed through the washing and absorption equipment, and the coal tar with high boiling point is used as the washing and absorption agent to recover the coal tar in the gas. After distillation, crude benzene and other high boiling point fractions are obtained. Crude benzene can be refined to obtain industrial grade benzene. The purity of benzene obtained by this method is relatively low, and the environmental pollution is serious, and the process is relatively backward.

  • 2. Extraction from crude oil

This method is a general method for extracting aromatics. Crude oil refining reforming here refers to the process of cyclization and dehydrogenation of aliphatic hydrocarbons to form aromatics. This is a craft developed during the Second World War. At 500-525 ° C and 8-50 atmospheres, various aliphatic hydrocarbons with boiling points between 60-200 ° C are transformed into benzene and other aromatics through dehydrogenation and cyclization with platinum rhenium catalyst. Benzene is separated by distillation after aromatic products are extracted from the mixture. These fractions can also be used as high octane gasoline. Now, more than 90% of the world’s total production comes from oil.

Therefore, aromatics are the product of petrochemical industry, which also means that the market trend of aromatics fluctuates with oil.

Frequently Asked Questions

What is hexane used for?

Hexanes are used for the manufacture of clothing, leather goods, and roofing glues. They are also used to extract cooking oils from seeds (such as canola oil or soy oil), to clean and degrease a variety of products, and in textile manufacturing.

Is hexane a good solvent?

When you are trying to dissolve a non-polar compound, hexane is a strong solvent; but, if you were trying to use hexane to dissolve a polar compound it would be very unsuccessful. With a polar compound, water would be a safer option than hexane, because water is polar and can interact more readily with the polar compound.

Why hexane is flammable?

N-Hexane is a crude oil-producing compound. Pure n-Hexane is a liquid with a slightly unpleasant odour. It is extremely flammable, and can be explosive in its vapours. The key application for n-Hexane-containing solvents is to extract vegetable oils from crops such as soybeans.

Does hexane evaporate?

Pure n-hexane is a liquid with a slightly unpleasant odour. This evaporates very quickly into the sun, and just partially dissolves in water. N-Hexane is extremely flammable, and can have volatile vapours.

Why hexane is used for extraction?

N-hexane is used as a solvent in solvent extraction for its attributes such as quick recovery, non-polar existence, low vaporizing latent heat (330 kJ / kg), and high solvent selectivity. Enzyme processing has significant potential to extract oil in the oilseed industry.

Where to buy n-Hexane?

n-Hexane: n-Hexane is one of the main products of our company. Its purity is between 60 ~ 85% (WT). It can be used as the solvent of catalyst in the production process of polyethylene and polypropylene. It is also a high-quality vegetable oil extraction solvent and rubber solvent. Sales inquiry: info@junyuanpetroleumgroup.com

Under less stringent conditions, petroleum ether can be replaced with n-Hexane. n-Hexane is also a mixture! HPLC grade only if the purity of n-Hexane is greater than or equal to 97%! 

Petroleum Ether
Petroleum ether is a mixture of lower alkanes. A mixture of pentane and hexane with a boiling point in the range of 30-60 ℃; The boiling point in the range of 90-120 ℃ is a mixture of heptane and octane. They are mainly used as organic solvents. Petroleum ether is extremely flammable and toxic. Special attention should be paid to safety during use and storage.

The elution intensity of agricultural residue n-hexane and petroleum ether is still different, and n-hexane is generally better

Comparison:
Petroleum ether: light petroleum product, with grades of 30 ~ 60 ℃ and 60 ~ 90 ℃, which is mainly composed of pentane and hexane. It can be prepared from platinum reforming raffinate or straight run gasoline by fractionation, hydrogenation or other methods.
N-hexane: it can be separated from petroleum fraction at 68.74 ℃.

CMR Bill of Lading

What is a CMR bill of lading? A CMR bill of lading is a bill of lading that complies with the guidelines of the international CMR Convention. CMR stands for Convention relative au Contrat de Transport International de Marchandises par Route (Convention on the International Carriage of Goods by Road).

What is the Convention on Contracts for the international carriage of goods by Road (CMR) required by foreign customers? How our Pentanes, Hexanes and Heptanes are transported by international roads to Europe, Russia, Uzbekistan, Afghanistan, Pakistan, India and Southeast Asian countries.

In short, “Convention on Contracts for the international carriage of goods by Road (CMR)” refers to the transport document issued in road transportation. The abbreviation of English convention renewable aucontract de transport international de marchandises par route is the international road cargo waybill. Sometimes the buyer’s certificate requirements are written as way bill / CMR / TIR, etc.

If CMR is explained in detail, what is an international convention first? International conventions refer to the common provisions of many countries specifically aimed at a certain field. Generally, they are the specific provisions between countries on the interests and risks of economy, politics, culture, law, technology and other aspects. After public discussion, they reach an agreement and abide by it jointly after signing. In popular terms, they are the rules of the game formulated by countries for a certain field, The content includes the rights and obligations of States parties signing the Convention, as well as the basis for how to solve problems after they occur.

The history and specific contents of the “Convention on Contracts for the international carriage of goods by road” contain a large amount of information, so it is inconvenient to elaborate here. Interested friends can search by themselves and learn the relevant provisions, rights and responsibilities in the Convention, especially friends majoring in international commercial law, international trade, supply chain and international logistics freight forwarding, which is conducive to solving a large number of business problems related to it in their work.  Our logistics partners operated the international road transportation business in Central Asia for many years. Customers often ask about this in their actual work. Here are three important contents summarized and brought to the attention of relevant practitioners.

The international road waybill is not a document of title. It is believed that many international trade and international logistics freight forwarders have understood that neither International Railway nor international road waybill can have property rights like ocean bill of lading, but some people still have problems in this link. After the goods arrive at the destination, the balance has not been recovered and the goods have been taken away. Therefore, before issuing the road waybill, we must do a good job in account control. If the balance is not recovered, we can control the cargo right through the designated transporter to avoid the empty of money and goods.

When transshipping landlocked countries through a third country, the receiving party requires CMR. As some countries are landlocked countries, in case of transshipment to inland countries through the ports of a third country, the consignor will encounter the request of the consignee to provide CMR for local customs clearance. Because most of such transportation will be blocked by the multimodal transport bill of lading issued to the end, even if CMR is involved, it will be ignored. Therefore, many practitioners do not understand the issuer and operation process of this document. If they encounter this matter, they can consult the freight forwarder.

Modify the CMR soft clause in the letter of credit. This link is related to Article 2. For example, if the CMR issuer is the road carrier of a third country, the CMR presentation will be used when the trade parties settle with the letter of credit, but the shipper may not be able to obtain the document. Therefore, in the verification stage, if such soft terms are found, it is necessary to discuss and modify them with the receiver in time to avoid problems in bank presentation. The specific modification method is negotiated by both parties, and there is no specific explanation here.

At present, China has acceded to the Convention on the international carriage of road vehicles in the field of international land transportation; In terms of international railways, China has acceded to the international railway freight transport agreement and the International Convention on railway freight transport; International maritime transport has acceded to the United Nations Convention on the carriage of goods by sea, namely the Hamburg Rules; International air transport has joined the Warsaw Convention and so on; In terms of multimodal transport, we have acceded to the United Nations Convention on international multimodal transport of goods and formulated a large number of domestic legal rules on warehousing and transportation. If we have the opportunity, we will also introduce them in detail.
It can be said that China has joined all major international conventions related to international transportation, making China’s logistics rules seamlessly connected with international rules. Only sound rules can keep domestic and international transportation channels smooth. In addition to abiding by them, we also need to use these rules to protect our interests in international trade.

International road transport of pentane,   hexane and heptane


Bill of lading

A bill of lading is a document issued by a carrier to acknowledge receipt of cargo for shipment. Although the term historically related only to carriage by sea, a bill of lading may today be used for any type of carriage of goods. Bills of lading are one of three crucial documents used in international trade to ensure that exporters receive payment and importers receive the merchandise. The other two documents are a policy of insurance and an invoice. Whereas a bill of lading is negotiable, both a policy and an invoice are assignable. In international trade outside the United States, bills of lading are distinct from waybills in that the latter are not transferable and do not confer title. Nevertheless, the UK Carriage of Goods by Sea Act 1992 grants “all rights of suit under the contract of carriage” to the lawful holder of a bill of lading, or to the consignee under a sea waybill or a ship’s delivery order.

 

What is a CMR bill of lading?

A CMR bill of lading is a bill of lading that complies with the guidelines of the international CMR Convention. CMR stands for Convention relative au Contrat de Transport International de Marchandises par Route (Convention on the International Carriage of Goods by Road). A bill of lading is a document that is linked to a shipment and describes what the carrier transports from A to B on behalf of the shipper. The CMR Convention is a treaty between European countries and some countries outside of Europe on the legal rules regarding the carriage of goods by road.  

What is a bill of lading?

A bill of lading (sometimes abbreviated as B/L or BOL) is a document that states that a carrier is transporting a load from A to B on behalf of the shipper. It is legal proof of the contract of carriage and is also used as a receipt, where the recipient signs the bill of lading. A bill of lading is linked to a shipment that consists of one or more goods that are loaded at one or more places for one client, that are transported with one motor vehicle or trailer, to one recipient. The bill of lading states which goods are contained in a shipment and where they need to be delivered. The bill of lading states whether special obligations must be met for these goods, for example in terms of hazardous substances. The weight is also stated, which can be used to check if a truck is not overloaded. There are different types of bills of lading. The most important is the CMR bill of lading, but there are also bills of lading that are only valid within one country.

The CMR Convention is an international agreement regarding the carriage of goods by road. It applies to the commercial transport of goods in international relations. Provided that at least one country (shipment or destination country) has acceded to the CMR Convention. It should be noted that it applies only to transport provided under a contract of carriage by cars, articulated vehicles, semi-trailers, and trailers.

CMR Convention – Important information

The CMR Convention is extremely useful because it unifies the transport documentation, transports carried out by successive carriers, the conditions of the contract for the carriage of goods by road, the carrier’s liability, the mode of complaints, and complaints, claims arising from the carriage. Entities authorized to operate in the field of international road transport are defined by the provisions of the national law of individual countries. In the case of Poland, this is determined by the Road Transport Act. It is worth noting that the CMR Convention is used when the transport is performed by states, organizations, or governmental institutions. Importantly, when applying the CMR Convention, the carrier is responsible for the actions taken by its employees as for its own.


Bill of lading

The proof of the conclusion of the contract of carriage under the CMR Convention is a consignment note. It is issued in triplicate (each copy has the same legal and evidentiary value). It is signed and stamped by both the sender and the carrier. The first of them takes the sender, the second accompanies the shipment and is intended for the recipient, while the third receives the carrier. Sometimes a fourth copy, so-called back copy, is issued for statistical purposes. If the goods are to be loaded on different vehicles or several batches of products are to be carried, both the sender and the carrier have the right to require the issue of so many waybills, how many vehicles should be used or how many types or batches of goods.

In the event of an irregularity, lack of information, or loss of the bill of lading, all costs incurred because of this by the carrier are borne by the sender. However, the carrier is obliged to check the condition of the goods together with their packaging, as well as the correctness of the details of the waybill with the number of copies, their numbers, and characteristics when receiving the goods.

What does the waybill contain?

The waybill should contain the following data:

a) place and date of issue;

b) name and address of the sender;

c) the name and address of the carrier;

d) place and date of acceptance of the goods for transport and the place of issue;

e) name and address of the recipient;

f) a commonly used description of the type of good and the manner of packaging, and for dangerous goods their generally accepted description;

g) the number of items, their characteristics, and numbers;

h) gross weight or otherwise expressed quantity of goods;

i) transport-related costs (transportable, additional costs, customs duties and other costs arising from the time of conclusion of the contract to the time of delivery);

j) instructions necessary to complete customs and other formalities;

k) a declaration that the carriage, regardless of any contrary clause, is subject to the provisions of this Convention.

When the CMR Convention does not apply

The CMR Convention does not apply to the carriage of postal items, corpses, and cargo belonging to displaced persons. Besides, it is not used when concluding shipping contracts. Contracts are deemed to be such, the essence of which is not to carry out the transport but only to its organization. The carrier does not have to carry out the transport personally. It follows that whether the convention is applicable or not is determined by the content of the undertaking. Therefore, if the basis of the contract is the performance of the transport, then the provisions of the Convention will apply.

Prices of Blowing Agents have fallen for the first time since January

14-MAR-22: the supply of Pentane foaming agent is sufficient and the demand is weak. Coupled with the increase of supply, the market of foaming agent products in the domestic market began to shift from tight supply and demand to oversupply. For the first time since January 2022, the price has fallen by – 1.09%.

Pentane is an aliphatic saturated hydrocarbon with stable chemical properties. It does not react with acids and bases at normal temperature and pressure. Pyrolysis occurs at high temperature above 600 ℃ or in the presence of appropriate catalyst to produce mixtures of propylene, butene, isobutene, butane and isopropane. Aluminum trichloride was used as catalyst for isomerization to produce 2-methylbutane. 2. Stability 3 Prohibited compounds: strong oxidant, strong acid, strong alkali, halogen 4 Polymerization hazard: no polymerization. Pentane products are widely used and can be used as foaming agents for expandable polystyrene and polyurethane foam systems. They are used in areas such as fluorine free refrigerators, freezers, cold storage and pipeline insulation.

The content of mixed pentane of Junyuan Petroleum Group is more than 99%; Distillation range: 34 ~ 39; Density: 620-630, acting on pentane foaming agent, oil blending pentane, medicine, pesticide intermediates, etc. Junyuan Petroleum Group sincerely welcomes people from all walks of life to consult, visit and negotiate business with strict quality assurance system and the most satisfactory service.

Application of Pentane Blowing Agent
Pentane is the main foaming agent used to produce polystyrene foam and other foams. Generally, mixtures of N -, I – and more and more cyclopentane are used for this purpose. Because of its low boiling point, low cost and relative safety, pentane is used as the working medium of geothermal power stations. It is also added to some refrigerant mixtures.
Pentanes are relatively cheap and are the most volatile alkanes that are liquid at room temperature, so they are usually used as solvents that can be easily evaporated in the laboratory. However, due to their nonpolarity and lack of functionality, they can only dissolve nonpolar and alkyl rich compounds. Pentane is miscible with most common nonpolar solvents, such as chlorocarbons, aromatics and ethers. They are also often used in liquid chromatography.

General pentane (hereafter, pentane) is a colorless, volatile and flammable liquid with a sweet or gasoline-like odor. Pentane consists of three isomers: n-pentane (the most important isomer), isopentane, and neopentane. n-Pentane is a constituent of crude oil and a component of the condensate from natural gas production. It is primarily obtained by fractional distillation of a petroleum stream (generally light virgin naphtha) obtained from the processing of crude oil. n-Pentane is used as a component of gasoline blends, as an aerosol propellant, in low temperature thermometers, as a blowing agent for foams (e.g. expandable polystyrene (EPS) and polyurethane (PUR)), and as a solvent (EU 2003). Isopentane is also used as a blowing agent, and neopentane is used in the manufacture of butyl rubber (ACGIH 2001).

Cyclopentane is a FLAMMABLE LIQUID and a FIRE HAZARD. IDENTIFICATION Cyclopentane is a clear liquid. It is used as a laboratory reagent, a solvent, and as an extraction agent in the paint and shoe industries. REASON FOR CITATION * Cyclopentane is on the Hazardous Substance List because it is cited by ACGIH, DOT, NIOSH, NFPA and EPA.

2-METHYLBUTANE (ISOPENTANE)†. Watery colorless liquid with a gasoline-like odor. * All sampling instructions above are recommended guidelines for OSHA Compliance Safety and Health Officers (CSHOs), please see the corresponding OSHA method reference for complete details. As Pentane; there is no specific OSHA PEL for 2-Methylbutane. CAS #: 78-78-4 Formula: C₅H₁₂

A blowing agent blend for foaming low density polyethylene foam consisting essentially of isopentane and at least one co-blowing agent, the co-blowing agent being either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof, and wherein the blowing agent blend includes from about 10 to about 99 mol % isopentane and the remainder consists essentially of the co-blowing agent. The blowing agent blend of claim above, wherein the co-blowing agent includes at least one physical co-blowing agent, the at least one physical co-blowing agent being ethane, n-propane, n-butane, isobutane, cyclopropane, nitrogen, argon, carbon dioxide, sulfur hexafluoride, nitrous oxide, dimethyl ether, 1,1-difluoroethane (HFC-152a), 1,1,1-trifluoroethane (HFC-143a), 1,1,1,2-tetrafluoroethane (HFC-134a), 1,1,2,2-tetrafluoroethane (HFC-134), 1,1,1,3,3-pentafluoropropane (HFC-245fa) or combinations thereof.

Presently, physical blowing agents more commonly used for making low density polyethylene (LDPE) foams are hydrocarbons such as isobutane or blends of isobutane and n-butane. Other hydrocarbons such as ethane and propane have been used more recently in making LDPE foams. The ability of isobutane, n-butane, propane, ethane and combinations thereof to give stable, low density foams depends on factors such as desirable solubility in low density polyethylene, and the ability of gas permeation modifiers to slow down the escape of such blowing agents. The resultant foam article (e.g., a sheet) using such blowing agents is frequently produced with at least some corrugation. Corrugation occurs when the radial rate of expansion is higher than the radial space available for the foam as it exits the die. Corrugation may be reduced to a certain extent by optimizing the foaming process and apparatus used in forming the foam with these blowing agents, but a low degree of corrugation or visible corrugation lanes often remain. The corrugation becomes more pronounced when a fluid with a very low boiling point (e.g., ethane or propane) is (a) used as the sole blowing agent or (b) present in an amount greater than about 5 mol % with a higher boiling fluid (e.g, isobutane). Corrugation also tends to occur more frequently in sheets (thickness of up to about ½ inch) as opposed to planks (thickness of greater than about an inch), and the degree and magnitude of corrugation increase as the foam density decreases. According to one embodiment of the present invention, a blowing agent blend for making polyolefin foams comprises isopentane and at least one co-blowing agent. The co-blowing agent is either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof. The blowing agent blend comprises less than about 99 mol % isopentane. The polyolefin foam may be a low density polyethylene foam. The blowing agent blend may consist essentially of isopentane and the co-blowing agent in which the blowing agent blend includes about 10 to about 99 mol % isopentane with the remainder consisting essentially of the co-blowing agent.

n -Hexane is a chemical made from crude oil. Pure n -hexane is a colorless liquid with a slightly disagreeable odor. It evaporates very easily into the air and dissolves only slightly in water. n -Hexane is highly flammable, and its vapors can be explosive.

2-Methylpentane, trivially known as isohexane, is a branched-chain alkane with the molecular formula C₆H₁₄. It is a structural isomer of hexane composed of a methyl group bonded to the second carbon atom in a pentane chain. Using a quantitative structure-activity relationship prediction model, 2-Methylpentane has a research octane number of 75, motor octane number of 77, and cetane number of 29.

n-Heptane is a colorless liquid with a mild, Gasoline-like odor. It is used as an industrial solvent and in petroleum refining processes. REASON FOR CITATION * n-Heptane is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, IRIS and NFPA.

n-Octane is used as a solvent and raw material for organic synthesis reactions and is a very important chemical in the petroleum industry. It is also widely used in the rubber and paper processing industries. Isooctane, along with other nalkanes and isoparaffins, is used in the blending of fuels to achieve desired antiknock properties.
