Abstract

Melamine is prepared by fusing cyanamide or dicyandiamide in a molten bath containing a relatively heat-stable salt of guanidine, biguanide or a substituted derivative of guanidine or biguanide, or a compound which will react with the cyanamide or dicyandiamide to produce such a salt, the reaction being carried out in presence of added ammonia. Thus dicyandiamide and ammonium chloride are fused together, further additions of dicyandiamide being made while a stream of ammonia is injected into the reaction mixture. In other examples guanidine hydrochloride is used as the salt.
