Abstract

PURPOSE: Acetonitrile, useful as a reaction solvent and raw material of organic synthesis, is purified with less energy consumption by organic synthesis, is purified with less energy consumption by converting allyl alcohol which exists in crude acetonitrile as an impurity into low-boiling allyl chloride, and distilling out the allyl chloride.
