1. Chemical analysis and instrument analysis
Acetonitrile has been used in recent years as an organic modifier and solvent for thin-layer chromatography, paper chromatography, spectral and polarographic analysis. Since high-purity acetonitrile does not absorb ultraviolet light at 200nm to 400nm, one application under development is as a solvent for high performance liquid chromatography (HPLC), which enables analytical sensitivity up to 10-9 levels.
2, hydrocarbon extraction separation solvent
Acetonitrile is a widely used solvent, mainly as a solvent in extractive distillation to separate butadiene from C4 hydrocarbons. Acetonitrile is also used in the separation of other hydrocarbons, such as propylene, isoprene and methylacetylene from hydrocarbon fractions. Acetonitrile is also used in some special separations, such as the extraction of separated fatty acids from vegetable oil and cod liver oil, so that the treated oil is pale, pure, and improved in smell, while the vitamin content is unchanged. Acetonitrile is also widely used as a solvent in the pesticide, textile and plastics sectors. [2]
3, semiconductor cleaning agent
Acetonitrile is a strong polar organic solvent, which has good solubility for grease, inorganic salt, organic matter and polymer compounds, and can clean off grease, wax, fingerprints, corrosives and flux residues on silicon wafers. Therefore, high purity acetonitrile can be used as a semiconductor cleaning agent.
