Acetonitrile

CAS NO.:75-05-8

MF:C2H3N

MW:41.05

Nature:A colorless, transparent liquid with an ether-like odor. It is miscible with water, methanol, methyl acetate, acetone, diethyl ether, chloroform, carbon tetrachloride, and vinyl chloride.

Application:It can be used as a solvent for extracting butadiene, a solvent for synthetic fibers, and a solvent for certain special coatings. In the petroleum industry, it is used as a solvent to remove tar, phenols, and other substances from petroleum hydrocarbons. In the oil and fat industry, it is used as a solvent for extracting fatty acids from animal and vegetable oils, and in medicine, it is used as a reaction medium for the recrystallization of steroidal drugs. When a polar solvent with a high dielectric constant is required, a binary azeotropic mixture of acetonitrile and water is often used: containing 84% acetonitrile, with a boiling point of 76℃. Acetonitrile is an intermediate in pharmaceuticals (vitamin B1) and fragrances, and a raw material for manufacturing triazine nitrogen fertilizer synergists. It is also used as a denaturing agent for alcohol. In addition, it can be used to synthesize ethylamine, acetic acid, etc., and has many uses in the textile dyeing and lighting industries.
