Acetonitrile, also known as Methyl Cyanide; Cyanomethane, is a colorless liquid that is highly volatile. It has a special odor similar to ether. It has excellent solvent properties and can dissolve a variety of organic, inorganic and gaseous substances. It has certain toxicity and is infinitely miscible with water and alcohol. Acetonitrile is a major organic intermediate that can undergo typical nitrile reactions and is used to make many typical nitrogen-containing compounds. Acetonitrile can be used to synthesize vitamin A, cortisone, solvents for carbonamines and their intermediates, as well as active medium solvents for the manufacture of vitamin B1 and amino acids. It also replace chlorinated solvents and used in vinyl coatings, as an extractant for fatty acids, as an alcohol denaturant, as a butadiene extractant and as a solvent for acrylonitrile synthetic fibers. It is also used in fabric dyeing, lighting, perfume manufacturing and photosensitive material manufacturing.
The most important use of Acetonitrile is as a solvent. For example, as a solvent for extracting butadiene, a solvent for synthetic fibers and a solvent for certain special coatings. A solvent used in the petroleum industry to remove tar, phenol, etc. from petroleum hydrocarbons. It is used as a solvent for extracting fatty acids from animal and vegetable oils in the oil and fat industry, and is used as a reaction medium for recrystallization of steroids in medicine. A binary azeotrope of acetonitrile with water is often used in polar solvents where high dielectric constant is required: 84% acetonitrile and 76℃ boiling point. Acetonitrile is a pharmaceutical (vitamin B1), an intermediate in perfumery, and a raw material for the manufacture of a triazine nitrogen fertilizer synergist. Also used as a denaturant for alcohol. In addition, it can also be used to synthesize ethylamine, acetic acid, etc. and has many uses in the fabric dyeing and lighting industries.
