Category n-Pentane | CAS# 109-66-0

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.

n–Pentane belongs to the fourth generation of hydrocarbon foaming agent, and is currently the best substitute product for chlorofluorocarbon foaming agent (141b). With the advantages of energy saving, environmental protection and high performance, it is widely used in cold storage insulation panels, Animal husbandry and fungus breeding plates, refrigerated vehicle insulation materials, pipeline insulation materials and other fields.

n-Pentane (n-Pentane) chemical formula C₅H₁₂, the fifth member of alkanes. There are 2 isomers of n-pentane: isopentane (boiling point 28°C) and neopentane (boiling point 10°C), the term “pentane” usually refers to n-pentane, its linear isomer.

Uses of n-Pentane: 1. Used as a low boiling point solvent, foaming agent in plastic industry, also used with 2-methylbutane as automobile and aircraft fuel, artificial ice, anesthetic, and synthesis of amyl alcohol and isopentane.

These solvents like pentanes, hexanes, heptanes and octanes need to be managed carefully to minimize risks of a fire or explosion, whether use occurs in the home or in an industrial setting—particularly during loading and unloading, storing, and when using in bulk.

Our successful risk management systems

Solvent storage, handling and processing conditions must be carefully controlled to prevent inci-dents. The control process is known as managing risk.

N-pentane (C5H12) is the fifth member of alkane. There are two isomers of n-pentane: Isopentane (boiling point 28 ° C) and neopentane (boiling point 10 ° C). The term “pentane” usually refers to n-Pentane, that is, its straight chain isomer.

There are two isomers of n-pentane, isopentane (boiling point 28 ° C) and neopentane (boiling point 10 ° C). Pentane is aliphatic saturated hydrocarbon with stable chemical properties and does not react with acids and bases at normal temperature and pressure. The mixture of propylene, butene, isobutene, butane and isopropane is produced by pyrolysis at high temperature above 600 ℃ or in the presence of appropriate catalyst.

The term “pentane” usually refers to n-Pentane, that is, its straight chain isomer. The boiling point of n-pentane is 36.1 ℃. Isopentane (isopentane, 2-methylbutane) is also known as 2-methylbutane, the chemical formula is C5H12.

The configurations of n-pentane molecular bond rotation include: total intersection, ortho dislocation, partial intersection and para dislocation. In the configuration of n-butane, the distance between the two methyl groups is the farthest, the interaction is the weakest and the internal energy is the lowest. The distance between the two methyl groups of ortho dislocation is closer, so the stability is slightly poor.

n-Pentane can be cracked to produce olefins, can be oxidized to anhydride, isopentane can be dehydrogenated to isoprene, and so on. Many excellent process routes can be designed.

Applications: n-Pentane can be used as foaming agent of EPS expandable polystyrene and desorbent agent of molecular sieve dewaxing wax process. Product features: using high quality light hydrocarbon raw materials, high purity and stable quality.
