Chemical Properties
Colourless transparent liquid with ether-like odour. Miscible with water, methanol, methyl acetate, acetone, ether, chloroform, carbon tetrachloride and vinyl chloride.
Uses
1、Chemical analysis and instrumental analysis
Acetonitrile has been used as organic modifier and solvent for thin layer chromatography, paper chromatography, spectral and polarographic analysis in recent years.
2、Hydrocarbon extraction and separation solvent
Acetonitrile is a widely used solvent, mainly as a solvent for extractive distillation method to separate butadiene from C4 hydrocarbons. Acetonitrile is also used for the separation of other hydrocarbons, such as the separation of propylene, isoprene and methyl acetylene from hydrocarbon fractions.
3、Synthesis of pharmaceutical and pesticide intermediates
Acetonitrile can be used for the synthesis of a variety of pharmaceutical and pesticide intermediates.
4、Semiconductor cleaning agent
Acetonitrile is an organic solvent with strong polarity, it has good solubility for grease, inorganic salt, organic matter and polymer compounds, it can clean off the grease, wax, fingerprint, corrosive agent and flux residue on the silicon wafer.
