ABSTRACT:
A process for the preparation of N-substituted alkylcarboxamides from a nitrile which comprises subjecting said nitrile to an aqueous non-catalytic hydrolysis to obtain an essentially equilibrium mixture consisting essentially of carboxamide and ammonium carboxylate salt, cooling said equilibrium mixture and isolating a crystalline mixture of carboxamide and ammonium carboxylate, reacting an alkylamine with the isolated mixture, filtering the reaction mass to separate insoluble carboxamide, and contacting the filtrate with a dehydration catalyst to obtain said N-substituted alkylcarboxamide in high yield.
