Abstract:
The present invention refers to a process for the purification of acetonitrile from crude acetonitrile or mixtures containing the same, which comprises the following operations:(a) transformation of hydrogen cyanide and acrylonitrile into compounds of higher molecular weight,(b) removal of most of the water in an azeotropic distillation column, and(c) separation of acetonitrile from the compounds of higher molecular weight and residual water in rectifying columns.
