Summary:
n-Pentane is an important organic chemical raw material, with the chemical formula C5H12. This article will provide a scientific introduction to the properties, uses, storage methods, and applications of n-pentane in the chemical industry.

N-pentane, as a member of the alkane family, occupies an important position in the chemical industry due to its unique chemical properties and wide range of applications. Its chemical formula C5H12 indicates that n-pentane is composed of 5 carbon atoms and 12 hydrogen atoms, and belongs to a type of straight chain alkanes.

1、 The properties of n-pentane

n-Pentane is a colorless and transparent liquid with a lower boiling point (about 36 ° C) and is prone to volatilization. Its isomers include isopentane and neopentane, but the term “pentane” usually specifically refers to n-pentane. N-pentane has stable properties at room temperature, but is prone to combustion reactions at high temperatures or near ignition sources.

2、 The use of n-pentane

n-Pentane has a wide range of applications in the chemical industry. Firstly, it can be used as a low boiling solvent to dissolve some substances that are not easily soluble in water. Secondly, n-pentane is also an important foaming agent in the plastic industry, which can help plastic materials form a uniform foam structure. In addition, n-pentane can also be used as a fuel for automobiles and airplanes, and its high calorific value and good combustion performance make it an ideal energy choice.

In addition to the above applications, n-pentane also plays an important role in gas chromatography analysis and can be used as a standard substance or reference liquid. At the same time, it can also be used to manufacture chemicals such as synthetic pentanol and isopentane, providing raw material support for chemical production.

3、 Storage method of n-pentane

Due to the flammable and explosive properties of n-pentane, special attention should be paid during storage. Firstly, it should be stored in a cool and ventilated warehouse, away from flames and heat sources. The temperature of the warehouse should not exceed 29 ℃ to avoid fire or explosion accidents. Secondly, storage containers should be kept sealed to prevent the volatilization or leakage of n-pentane. In addition, n-pentane should be stored separately from oxidants and other substances to avoid chemical reactions.

Emergency leak handling equipment and appropriate containment materials should be equipped in the storage area, so that measures can be taken quickly for disposal in the event of a leak. At the same time, explosion-proof lighting and ventilation facilities should also be used to ensure the safety of the storage area.

4、 Summary

n-Pentane, as a multifunctional organic chemical raw material, plays an important role in the chemical industry. By understanding its properties, uses, and storage methods, we can better utilize n-pentane to provide support for chemical production. At the same time, we should also pay attention to its safe storage issues to ensure that no safety accidents occur during use.

Certificate of inspection (English Name: Certificate of inspection for Pentane), Pentane inspection certificate is used to prove the quality, quantity, weight or hygiene of goods respectively.
The pentane inspection certificate is a necessary certificate document for import customs declaration. Different goods require different types of relevant certificates. What the customs declaration company needs to do is to confirm the required certificate type according to the HS commodity code of the goods, and then handle the preparation for customs declaration respectively.
Pentane Certificate Issued by:
In China, the supporting documents of the inspection certificate shall be issued by the China Import and Export Commodity Inspection Bureau. If there are no special requirements and provisions in the contract or letter of credit, they can also be issued by the import and export company or production enterprise under different circumstances. However, it should be noted that the name of the certificate and the items listed or inspection results shall be the same as those specified in the import contract and letter of credit, There is nothing wrong with acting according to the import commercial contract.
The commodity inspection certificate is related to the economic responsibilities and rights and interests of all parties concerned, and its functions are as follows:

Quality Certificate

1. As the basis for whether the quality, weight, quantity, packaging and sanitary conditions of the goods delivered by the seller comply with the provisions of the contract.
2. As a certificate for the buyer to raise objections to quality, quantity, weight and packaging, reject the goods and claim compensation.
3. As one of the documents for the seller to negotiate the payment with the bank.
4. As a valid certificate checked and released by the customs of the exporting and importing countries.
5. As the basis for proving the actual condition of goods during loading, unloading and transportation and clarifying the attribution of responsibility.
   The commodity inspection certificate plays the role of fair proof. It is the main basis for the buyer and the seller to hand over the goods, settle the payment for goods, deal with claims and settle claims. It is also an effective certificate for customs clearance, tax payment and freight settlement.

Pentane raw materials are mainly from oil refineries. Pentane products are widely used as blowing agent, solvent and chemical raw materials. At present, there are 36 high-purity isopentane, n-pentane, cyclopentane and mixed pentane blowing agents in China, with a production capacity of about 150 kt / A. the annual consumption of pentane in China is nearly 66 KT, of which the annual consumption of pentane is about 66 KT, The consumption of PEPS pentane foaming agent accounts for 45% of the total consumption; the consumption of polyurethane foaming agent accounts for about 50% of the total consumption; the consumption of linear low-density polyethylene pentane carrier solvent accounts for about 5% of the total consumption. Domestic pentane supply exceeds the demand, but the supply of high-grade products is insufficient. Therefore, the newly-built unit during the 10th Five Year Plan period must adopt domestic advanced technology, Adopt cheaper feed gas to ensure product quality, reduce production cost as much as possible, strengthen market development and improve market competitiveness of products.
