1. Oxidation reaction of n-hexane: It is extremely flammable, and its vapor can form an explosive mixture with air. It is very easy to burn and explode when exposed to open flames and high heat. It reacts violently with oxidants and even causes combustion. In a fire scene, heated containers are at risk of explosion. Its vapor is heavier than air and can spread to a considerable distance at a lower level. It will ignite back when exposed to open flames.

n-Hexane burns in oxygen to produce carbon dioxide and water:

2. Compared with the octane number of n-hexane, the octane number of isoparaffins with the same carbon number is several dozen units higher, and isomerized oil also has the advantages of low sulfur content, no olefins, aromatics and benzene. Therefore, converting n-paraffins into isoparaffins is an effective means to improve the quality of gasoline. Commonly used catalysts for catalyzing the isomerization reaction of n-hexane include aluminum chloride type, molecular sieve type, and solid superacid type catalysts loaded with precious metals.

Uses

It is mainly used as a solvent, a reference substance for chromatographic analysis, a paint thinner, a medium for polymerization reactions, etc. It can also be used in organic synthesis.
