ABSTRACT:
A process for preparing 3-amino-1,2,4-triazole by reacting hydrazine hydrate, cyanamide and formic acid to form aminoguanidine formate and cyclizing the formate, wherein hydrazine hydrate and formic acid are simultaneously added to the cyanamide at 0.degree. to 10.degree. C. and a pH of 6 to 7, maintaining the mixture at 60.degree. to 100.degree. C. and a pH of 7 to 8 to form aminoguanidine formate, evaporating the aminoguanidine formate solution at 30.degree. to 60.degree. C. to a solids content of 100 to 700 g/L, filtering and washing the formate to a dicyandiamide content below 0.25%, and heating the formate at 110.degree. to 200.degree. C. to obtain the aminotriazole.
