ACETONITRILE

CAS: 75-05-8
APPEARANCE: colourless liquid is the simplest organic nitrile
Technical acetonitrile is used as a raw material for the synthesis of chemical products, for the production of vitamin B1, in the textile and petrochemical industry, as a solvent of organic compounds, as an extractive agent for separation of hydrocarbons by extractive distillation, and for the removal of tars, phenols and colorants from hydrocarbons
