Abstract
A process for the preparation of compounds containing nitrile functions and, more specifically, compounds containing two nitrile functions, such as succinonitrile and adiponitrile, is described. A process for preparing dintrile compounds obtained by reacting ammonia with an aqueous solution of a dicarboxyl compound in the presence of a silicon orthophosphate catalyst is also described.
