N-hexane gas is also known as hexane, with a molecular formula of C6H14 and a molecular weight of 86.2. It belongs to the class of straight-chain saturated aliphatic hydrocarbons and is obtained by cracking and fractionation of crude oil. It is a colorless, gasoline-smelling, volatile liquid with a melting point (MP) of 95°C, a boiling point of 68.95°C, and a vapor density of 2.97 (air = 1). It is almost insoluble in water and easily soluble in chloroform, ether, and ethanol. N-hexane is an organic solvent and is commonly used in the production of rubber, pharmaceuticals, perfumes, shoes, leather, textiles, furniture, paints, and other production processes. In recent years, n-hexane has been used as a diluent in the production of adhesives or as an organic cleaner, becoming the culprit of occupational n-hexane poisoning incidents in my country.

Hydrocarbons

N-hexane gas is a naturally occurring hydrocarbon in petroleum and one of the main components of petroleum ether and naphtha. It is a colorless, transparent liquid at room temperature with a slight smell of petroleum. It is volatile and its vapor is heavier than air. It forms an explosive mixture with air, with an explosion limit of 1.18% to 7.4% (volume fraction). N-hexane is widely used as a solvent for edible oil extraction, rubber solvent, artificial leather finishing agent, precision device cleaning agent, clothing detergent, pharmaceutical tablet detergent, and mixed solvent preparation.

N-hexane gas function and use

N-hexane is an organic solvent with good viscosity. It is often used in rubber food, pharmaceuticals, perfumes, shoemaking, tape, ball making, grinding, leather, textiles, furniture, paint industry, or as a dilution, or as a cleaning solvent, or as a viscose. In addition, it can be a solvent for extracting seed oil (such as soybean oil, cottonseed oil, linseed oil (flax), peanut, safflower oil (safflower), etc.); it can also be a raw material for making polymers; such as polypropylene (polypropylene) and polyethylene (polyethylene).
