Acetonitrile is used mainly as a solvent in the purification of butadiene in refineries. Specifically, acetonitrile is fed into the top of a distillation column filled with hydrocarbons including butadiene, and as the acetonitrile falls down through the column, it absorbs the butadiene which is then sent from the bottom of the tower to a second separating tower.

Propionitrile is a solvent similar to acetonitrile but with a slightly higher boiling point. It is a precursor to propylamines by hydrogenation. It is a precursor to propylamines by hydrogenation. It is a C-3 building block in the preparation of the drug flopropione by the Houben-Hoesch reaction .
Trichloroacetonitrile can be obtained by chlorination of acetonitrile on a zinc, copper and alkaline earth metal halide-impregnated activated carbon catalyst at 200–400 °C with a 54% yield. [ 3 ] The high temperatures required by this process favours the formation of byproducts, such as tetrachloromethane .
