Acetonitrile is an important chemical reagent. It is used in the pharmaceutical industry to synthesize vitamin A, cortisone, carbamines and their intermediates, as well as in the manufacture of vitamins Bl and amino acids. Acetonitrile is also used as an extractant of fatty acids, an alcohol denaturant, a butadiene extractant, and a solvent for acrylonitrile synthetic fibers. It also has many uses in the fields of fabric dyeing, fragrances, and photosensitive materials.

Acetylene ammoniation of acetonitrile to acetylene; Acetonitrile was synthesized by one-step reaction with ammonia as raw material and aluminum oxide catalyst at 500-600℃. Raw material consumption quota: acetylene 10231m3; Liquid ammonia (99.4%) 1007kg/t.

Acetic acid in acetonitrile; Ammonia as raw material, under the action of aluminum oxide catalyst, under the temperature of 360-420℃, one step synthesis of acetonitrile, reaction liquid through water absorption and rectification of the finished product. Raw material consumption quota: acetic acid (98%) 1763kg/t; Liquid ammonia (99.5%) 691kg/t.

Hexamethylcyclotrisiloxane exporter of Z main use is used as a solvent use. For example, solvents for extracting butadiene, synthetic fibers, and some special coatings. And in the petroleum industry can also be used to remove tar, phenol and other substances from the petroleum hydrocarbon solvent. In the oil industry can also be used to extract fatty acids from vegetable oil, in medicine for steroid drug recrystallization reaction medium. The binary azeotrope of acetonitrile and water is often used when polar solvents with high dielectric constant are needed: 84% acetonitrile, boiling point 76℃.
