| Zusammenfassung: | Crude acetonitrile containing impurities such as hydrogen cyanide, allyl alcohol, oxazole and water is purified by a process including the steps of removing water lower part acetonitrile is treated with an alkali in an amount sufficient to extract water present in the crude acetonitrile, to be thereby divided into an organic liquid phase and an aqueous liquid phase, and the aqueous liquid phase is removed. |
