| production method | 1. it is prepared by heating reaction with thiourea and hydrazine hydrate as raw materials. 2. Hydrazine sulfate is prepared from hydrazine hydrate and sulfuric acid, which reacts with ammonium thiocyanate to form hydrazine thiocyanate, and then reacts with acetaldehyde to obtain thiosemicarbazide by hydrolysis. |
