What is n-Heptane and why is it important for chemistry?

by Manufacturers, Producers, Suppliers Jan 27, 2024

n-Heptane is a pure form of heptane, a common solvent and fuel component. It has a special role in measuring the octane rating of gasoline and in separating chiral compounds.

Heptane is a simple organic compound with the chemical formula C$_7$H$_{16}$. It is a colorless liquid that smells like gasoline and is highly flammable. Heptane is widely used as a solvent in laboratories and industries, as it can dissolve many non-polar substances. It is also a component of gasoline, as it can be easily refined from crude oil.

However, not all heptane molecules are the same. There are different ways to arrange the seven carbon atoms and the 16 hydrogen atoms in a heptane molecule, resulting in different shapes and properties. These different forms of heptane are called isomers, and there are nine of them in total.

One of the isomers of heptane is n-heptane, which stands for normal heptane. This is the simplest and most symmetrical form of heptane, where the seven carbon atoms are arranged in a straight chain. n-Heptane has some unique characteristics that make it important for chemistry.

First, n-heptane is the standard for measuring the octane rating of gasoline. The octane rating is a measure of how well a fuel can resist knocking, which is a phenomenon where the fuel ignites too early in the engine, causing damage and reducing efficiency. n-Heptane is very prone to knocking, as it burns very quickly and explosively. Therefore, it is assigned a octane rating of zero, meaning the worst possible fuel for an engine. On the other hand, iso-octane, another isomer of octane (C$_8$H$_{18}$), is very resistant to knocking, as it burns more slowly and smoothly. Therefore, it is assigned a octane rating of 100, meaning the best possible fuel for an engine. Other fuels are compared to these two extremes, and their octane rating is calculated as the percentage of iso-octane in a mixture with n-heptane that has the same knocking behavior. For example, a gasoline with an octane rating of 87 means that it behaves like a mixture of 87% iso-octane and 13% n-heptane.

Second, n-heptane is useful for separating chiral compounds. Chiral compounds are molecules that have two forms that are mirror images of each other, like your left and right hands. These forms are called enantiomers, and they can have different effects on living organisms. For example, one enantiomer of a drug may be beneficial, while the other may be harmful. Therefore, it is important to be able to separate and identify the enantiomers of a chiral compound. One way to do this is by using a chiral column, which is a tube filled with a material that can distinguish between the enantiomers. The chiral compound is dissolved in a solvent, such as n-heptane, and passed through the column. The enantiomers will interact differently with the material, and will come out of the column at different times. This is called chromatography, and it is a widely used technique for separating and analyzing mixtures.

n-Heptane is a good solvent for chiral chromatography, as it is non-polar and does not interfere with the interactions between the enantiomers and the material. However, n-heptane alone is not enough to separate the enantiomers, as it may not have enough eluting power, which is the ability to push the compounds through the column. Therefore, n-heptane is often mixed with other solvents, such as ethanol or isopropanol, which have more eluting power and can affect the selectivity and resolution of the separation. The choice of the solvent mixture is a key step in chiral analysis, and it depends on the properties of the chiral compound and the column material.

In summary, n-heptane is a pure form of heptane, a common solvent and fuel component. It has a special role in measuring the octane rating of gasoline and in separating chiral compounds. n-Heptane is an example of how a simple molecule can have important applications in chemistry and beyond.

The Challenge of n-Heptane Supply: A Popular Solvent with a Volatile Market

by Manufacturers, Producers, Suppliers Jan 20, 2024

n-Heptane is a chemical compound with the formula C7H16, consisting of a chain of seven carbon atoms and 16 hydrogen atoms. It is a colorless, flammable liquid that belongs to the group of alkanes, which are the simplest and most common type of hydrocarbons. N-Heptane is widely used as a solvent in various industries, such as paints, coatings, adhesives, pharmaceuticals, and oil extraction. It is also used as a reference fuel to measure the octane rating of gasoline, as it has the lowest octane number of zero. This means that n-heptane burns more easily and causes engine knocking, which is a problem for gasoline engines. Therefore, gasoline is blended with other hydrocarbons that have higher octane numbers to prevent knocking and improve engine performance.

N-Heptane is mainly produced from the refining of crude oil, which is a complex mixture of different hydrocarbons. N-Heptane can be separated from crude oil by a process called fractional distillation, which involves heating the crude oil and collecting the different fractions that boil at different temperatures. N-Heptane is one of the components of the light naphtha fraction, which boils between 30°C and 200°C. N-Heptane can also be synthesized from other hydrocarbons, such as ethylene, propylene, and butane, by a process called oligomerization, which involves combining smaller molecules into larger ones.

The supply and demand of n-heptane are influenced by various factors, such as the price and availability of crude oil, the demand from downstream industries, the environmental regulations, and the geopolitical situations. The price of n-heptane is closely linked to the price of crude oil, as it is one of the main raw materials for its production. The price of crude oil is determined by the balance between the global supply and demand, as well as the market expectations and speculations. The supply of crude oil depends on the production capacity and output of the major oil-producing countries, such as Saudi Arabia, Russia, and the United States. The demand for crude oil depends on the economic growth and energy consumption of the major oil-consuming countries, such as China, India, and the European Union. The price of crude oil can also be affected by unexpected events, such as natural disasters, wars, and sanctions, that disrupt the normal production and transportation of oil.

The demand for n-heptane is driven by the demand from the downstream industries that use it as a solvent or a fuel additive. The demand for n-heptane can vary depending on the season, the region, and the industry. For example, the demand for n-heptane as a solvent for paints and coatings can increase in the summer, when the construction and renovation activities are more active. The demand for n-heptane as a solvent for oil extraction can increase in the winter, when the viscosity of the crude oil is higher and needs to be reduced for easier pumping. The demand for n-heptane can also differ across regions, depending on the local preferences and regulations for gasoline quality. For example, some countries, such as China and India, have stricter standards for gasoline octane rating, which require more n-heptane to be blended with gasoline to lower its octane number and reduce its emissions.

The supply and demand of n-heptane can also be influenced by the environmental regulations and policies that aim to reduce the greenhouse gas emissions and improve the air quality. These regulations and policies can affect the production and consumption of n-heptane in different ways. For example, some regulations, such as the Clean Air Act in the United States, can limit the amount of n-heptane that can be used as a solvent or a fuel additive, as it contributes to the formation of ozone and smog, which are harmful to human health and the environment. On the other hand, some policies, such as the Renewable Fuel Standard in the United States, can encourage the use of n-heptane as a solvent or a fuel additive, as it can help to increase the blending of biofuels, such as ethanol and biodiesel, with gasoline and diesel, which are more environmentally friendly.

The challenge of n-heptane supply is to balance the supply and demand of this important chemical compound in a volatile and uncertain market. The producers and consumers of n-heptane need to monitor the market trends and dynamics, and adjust their production and procurement strategies accordingly. The producers of n-heptane need to optimize their production capacity and output, and diversify their sources of raw materials and markets. The consumers of n-heptane need to secure their supply contracts and inventories, and explore alternative solvents and fuels. The governments and regulators need to provide clear and consistent policies and regulations, and foster cooperation and coordination among the stakeholders. The researchers and innovators need to develop new and improved technologies and processes, and discover new and better applications and uses of n-heptane.

by Manufacturers, Producers, Suppliers Aug 18, 2022

Introduction to Malaysia ASEAN Free Trade Certificate of Origin (FORM E)

Malaysia certificate of origin, also known as China’s certificate of origin for export to Malaysia, can also be called Malaysia ASEAN certificate of origin Form E. Malaysia ASEAN certificate of origin Form E is issued by China entry exit inspection and Quarantine Bureau and consists of one original and three copies. The main purpose of applying for ASEAN certificate of origin Form E for export to Malaysia is to obtain the tariff preference of the Malaysian authorities when the goods are imported into Malaysia, so as to enable the smooth customs clearance of this batch of goods.

The Malaysian certificate of origin Form E cannot have double headers. The header of the trader or factory can only be displayed under the description of the goods in the seventh column of the Form E certificate of origin, and cannot be displayed in the exporter column in the first column of the certificate of origin. For export declaration, the header of the trader or factory can be used normally.

The following points shall be noted when exporting Form E certificate of origin to Malaysia:

1. Consignee name and address cannot be bank name.

2. The departure date, ship name, port of departure and port of destination must be correct and consistent with the bill of lading.

3. The amount on the certificate of origin must show FOB amount.

Malaysian import tariff system

As a member of the world trade organization, Malaysia’s tariff level is generally low. Although the tariff rate of most items is lower than 25%, the value range of tariff rate is very wide. The tariff on basic food is very low, no more than 5%. The average tax rate for major goods is about 5%. The average tax rate of intermediate products and transportation equipment is less than 20%. The tax rate of consumer goods is higher, some as high as 60%. The tariff rate for high priced motor vehicles is higher than 100%. In short, of its total of about 600 imported items, only 91 have a tariff rate of more than 50%. As a member of the ASEAN Free Trade Area (AFTA) under construction, Malaysia’s tariff reduction will implement the “generally effective preferential tariff” (CEPT) plan in the AFTA regulations. The main imported products of Malaysia are divided into three categories. The first category is raw materials and means of production, including electronic components, textiles, plastics, machine parts, oil, chemical fertilizers, pesticides and food, accounting for 42.6% of the total import volume; The second category is mechanical equipment, including metal products, mechanical transport equipment, electronic instruments, heavy machinery and telecommunications equipment, accounting for 34.5% of the total import volume; The third category is daily necessities, including motorcycles, bicycles, jewelry and food, accounting for 21.9% of the total imports.

A Blowing Agent for the Polyurethane Foams

by Manufacturers, Producers, Suppliers Aug 18, 2022

Cyclopentane – A Blowing Agent for the Polyurethane Foams
Cyclopentane is usually used as a new, more environmentally friendly insulation material in the manufacture of select refrigerators and freezers.
Cyclopentane is a blowing agent for the polyurethane foams that are used to insulate refrigerators and freezers.
Unlike some other chemicals used to insulate refrigerators, cyclopentane does not contain hydro-fluorocarbons (HFCs). Using cyclopentane results in significant reductions in equivalent CO2 emissions.
The most common foam-blowing agents currently used in the U.S. are R134a and R245fa. These industry-standard insulations can have a global warming potential (GWP) as high as 1300 (134a) and 950 (245a). In contrast, the foam-blowing agent cyclopentane has a GWP of approximately 10. When it comes to GWPs, the lower the number is, the better it is for the environment, so cyclopentane is clearly the more environmentally friendly choice.
Cyclopentane increases the efficiency of the insulation foam by approximately 4 percent over the R134a foam currently used in most refrigeration products.
Cyclopentane has been very popular as a blowing agent in Europe since the early 1990s, but the cost of retrofitting existing production facilities and the lack of U.S. regulations restricting the use of HFCs has delayed implementation in the U.S. However, there are other manufacturers currently selling refrigerators in the U.S. that use cyclopentane.
Compared to other insulating foams, cyclopentane is competitively priced and relatively easy to produce.
Like many gases, in its pure form, cyclopentane is a highly evaporative and flammable material. However once foamed, the unit is no more hazardous than a unit foamed with other blowing agents. As with any of our manufacturing processes, we’ve integrated a wide variety of redundant engineering and operational safeguards.

Common questions about cyclopentane
Q: What is this new material being used in the foam insulation?
A: The new material is called cyclopentane, a highly evaporative gas that is used to apply the foam insulations in refrigeration units.
Q: What is cyclopentane?
A: Cyclopentane is a blowing agent for the polyurethane foams that are used to insulate refrigerators and freezers.
Q: What are the benefits of using cyclopentane instead of other materials?
A: From an environmental perspective, unlike some other chemicals used to insulate refrigerators, cyclopentane does not contain hydro-fluorocarbons (HFCs). Using cyclopentane results in significant reductions in equivalent CO2 emissions.
Q: What foam-blowing agents are most commonly used in the U.S.? How is cyclopentane different?
A: The most common foam-blowing agents in the U.S. right now are R134a and R245fa. These two industry-standard insulations can have a global warming potential (GWP) as high as 1300 (134a) and 950 (245a). Comparatively, the foam-blowing agent cyclopentane has a GWP of approximately 10. When it comes to GWPs, the lower the number is, the less adverse impact on the environment, so cyclopentane is clearly a better choice.
Q: Are there significant insulating advantages, as well?
A: Yes, cyclopentane is approximately 4 percent more efficient than the R134a foam we currently use in most of our products.
Q: Do other refrigerators available in the U.S. market use cyclopentane?
A: There are other manufacturers currently selling refrigerators in the U.S. that use cyclopentane.
Q: Why hasn’t cyclopentane caught on in the United States?
A: It has been very popular as a blowing agent in Europe since the early 1990s, but the cost of retrofitting existing production facilities and the lack of U.S. regulations restricting the use of HFC’s has delayed implementation in the U.S.
Q: Is it more expensive than other insulating materials?
A: It is competitively priced and relatively easy to produce.
Q: Is it dangerous?
A: Like many gases, in its pure form, cyclopentane is a highly evaporative and flammable material. However once foamed, the unit is no more hazardous than a unit foamed with other blowing agents. As with any of our manufacturing processes, we’ve integrated a wide variety of redundant engineering and operational safeguards.
