With water, methanol, methyl acetate, acetone, ether, chloroform, carbon tetrachloride and vinyl chloride miscible. Forms an azeotrope with water containing 84% acetonitrile, azeotropic point 76 ℃.
The main purpose:	Acetonitrile main purpose is as a solvent. Such as butadiene extraction solvents, synthetic solvents and some special paint solvents. The solvent for removing tar, phenol and other substances from petroleum hydrocarbons in the oil industry. As driven vegetable oil fatty acids extracted from the solvent in the oil industry, in medicine for recrystallization steroidal drug reaction medium. Acetonitrile is often used when the formation of water in a polar solvent of high dielectric constant required binary azeotropic mixtures: acetonitrile containing 84%, boiling point 76 ℃. Acetonitrile pharmaceutical (vitamin B1), spices intermediates, manufacturing triazine nitrogenous fertilizer synergist raw materials. Also used as a denaturant for ethyl alcohol. Can also be used ethylamine, acetic acid, etc., and in textile dyeing, light industry, there are many uses.
