Industrial Alkane

Hexane, the molecular formula C6H14, is an alkane containing 6 carbon atoms, including five isomers: n-hexane, 、2-methylpentan 3-methylpentan , 2,3-dimethylbutane and 2,2-dimethylbutane . Among them, n-hexane can be used as a good organic solvent and is widely used in chemical organic synthesis, vegetable oil leaching, mechanical equipment surface cleaning and decontamination. Hexane is liquid at room temperature.

The density of hexane is 0.672, the melting point is -95℃, the boiling point is 68-70℃, and the flash point is -22℃. Hexane is insoluble in water, but is easily soluble in most organic solvents such as ethanol and ether. Hexane is extremely flammable and will undergo substitution reaction with halogen。

1. Oxidation reaction: Hexane is extremely flammable, and its vapor and air can form an explosive mixture. It is very likely to burn and explode when exposed to open flames and high heat. A strong reaction occurs when contacting an oxidant, and even causes combustion. In a fire, the heated container is at risk of explosion. The vapor is heavier than air and can spread to a considerable distance from a lower place. When exposed to open flames, it will cause backfire. The combustion products are carbon dioxide, water and carbon monoxide (carbon monoxide is produced when it is not completely burned).

The chemical equation for complete combustion of hexane is: 2C6H14+19O2=12CO2+14H2O (conditions are ignition)

2. Substitution reaction: Like other alkanes, hexane can also undergo substitution reaction with halogen (F, Cl, Br, I) . There are many types of compounds produced by substitution. Therefore, hexane must be stored away from halogen (such as fluorine, chlorine, bromine, and iodine).
