    Abstract: 1,2,4-triazole is obtained by cyclization of N,N'-diformylhydrazine with ammonia in the presence of formamide. The amount of ammonia required is either formed in situ from thermally decomposable ammonium salts, or supplied by feeding in gaseous ammonia. Simultaneously, the water of reaction is constantly distilled off from the system.
