Chemical properties Colorless; transparent liquid; has a unique fragrance similar to ether; miscible with water, methanol, methyl acetate, acetone, ether, chloroform, carbon tetrachloride and vinyl chloride miscible.
Uses Acetonitrile is the raw material for preparing orthoacetate. It is also used as the intermediate of producing DV-acid methyl ester and 2-chloro-3,3,3-trifluoro-1-propenyl-2,2-dimethyl cyclopropanecarboxylate. It can also be used as the raw materials of making pyrimidine derivatives which is the intermediate of sulfonylurea herbicides. Moreover, it can be used for making vitamin B1 in the field of pharmaceutical industry and as the extraction agent of C4 fraction in the synthetic rubber industry. 
Used as nitrile rubber monomer; Used for pharmaceutical industry and extraction of carbon IV.
As standard reference in chromatographic analysis; also as solvent and stationary phase for gas chromatography.
The major application of acetonitrile is as a solvent such as solvents for butadiene extraction, solvent for synthetic fibers and solvents for some special paints. In the oil industry, acetonitrile is used as the solvent for removing tar, phenol and other substances from petroleum hydrocarbons. It is also used as the solvent for extracting fatty acids from vegetable and animal oil in the fatty acid industry, and used as the reaction medium of the recrystallization of steroidal drugs in medicine industry. The binary azeotropic mixtures of acetonitrile and water are often used when a polar solvent of high dielectric constant is demanded: containing 84% acetonitrile, boiling point: 76 °C. Acetonitrile is used as the intermediate of pharmaceutical (vitamin B1) and spices, as the raw materials for making the synergist of triazine nitrogenous fertilizer, and also as a denaturant for ethyl alcohol. Moreover, it can also be used for synthesizing ethylamine, acetic acid, etc., and have many applications in textile dyeing and light industry.
It is used as the solvent of most inorganic compounds. It is also used as the solvent for spectrophotometric measurement, as a non-aqueous solvent, and as the diluents for determination of the carboxyl group. Furthermore, it is also applied in recrystallization of steroids and extraction of fatty acid, and also used as the solvents of High pressure liquid chromatography (HPLC).
