1. Chemical analysis and instrumental analysis
Acetonitrile has been used as an organic modifier and solvent for thin-layer chromatography, paper chromatography, spectroscopy and polarographic analysis in recent years.
2. Solvent for extraction and separation of hydrocarbons
Acetonitrile is a widely used solvent, mainly used as a solvent for extractive distillation to separate butadiene from C4 hydrocarbons.
3. Semiconductor cleaning agent
Acetonitrile is an organic solvent with strong polarity. It has good solubility in grease, inorganic salts, organic matter and polymer compounds. It can clean grease, wax, fingerprints, corrosives and flux residues on silicon wafers.
4. Organic Synthesis Intermediate
Acetonitrile can be used as a raw material for organic synthesis, a catalyst or a component of a transition metal complex catalyst.
5. Agrochemical Intermediates
In pesticides, it is used to synthesize pyrethroid insecticides and pesticide intermediates such as etoxicarb.
6. Dyestuff Intermediates
Acetonitrile is also used in fabric dyeing and coating compounds.
