Abstract

A method for purifying acetonitrile said method comprising steps for adding an alkali to water containing acetonitrile that has been produced by an ammoxidation reaction reacting the alkali therewith supplying the resulting reaction mixture to a first distillation column further mixing the obtained distillate with the alkali separating the resulting mixture into an acetonitrile phase and an aqueous phase removing the aqueous phase and supplying the acetonitrile phase into a second distillation column wherein the steam distilled from the second distillation column is utilized as a heat source for a reboiler of the first distillation column.
