Abstract: 2-Amino-5-mercapto-1,3,4-thiadiazoles can be produced in very high yields from thiosemicarbazides and carbon disulfide in aqueous phase by working in the presence of the corresponding ammonium salt of bis-2,5-mercapto-1,3,4-thiadiazole at a temperature above 40 DEG C. Preferably the process is carried out in the presence of the mother liquor from a previous reaction.

Abstract: For the production of thiosemicarbazide, hydrazine is reacted with hydrogen cyanide and sulphur to form hydrazine thiocyanate, which is converted into the thiosemicarbazide by treatment at elevated temperature. The reaction is carried out with advantage in a polar solvent.

Abstract: 2-amino-5-mercap-to-1,3,4-thiadiazoles can be produced, in very high yields, from thiosemicarbazides and carbon disulphide in aqueous phase when the reaction is carried out in the presence of the corresponding ammonium salts of bis-2,5-mercapto-1,3,4-thiadiazoles at temperatures above 40.degree.C. The reaction is carried out preferably in the presence of the mother liquor of preceding reactions.
