A process for preparing triaminoguanidine nitrate from relatively impure -99 percent)/commercial guanidine nitrate and commercial grade aqueous hydrazine (50-64 weight percent) in alcohol by: (1) adding enough hydrazine to form monoaminoguanidine nitrate, diaminoguanidine nitrate, or mixtures thereof, (2) physically removing the alcohol insoluble, solid impurities from the solution, (3) adding the remainder of the hydrazine needed to form triaminoguanidine nitrate, (4) adding nitric acid to adjust the pH to from 4.5 to 5.5, and (6) isolating the product triaminoguanidine nitrate.
从相对不纯(99%)/商业级硝酸胍和50-64重量%的商业级水合肼(50-64重量%)的酒精中制备三胍硝酸盐的过程为:(1)添加足够的水合肼形成一胍硝酸盐,二胍硝酸盐或其混合物,(2)从溶液中物理去除不溶于酒精的固体杂质,(3)添加剩余所需的水合肼以形成三胍硝酸盐,(4)加入硝酸以调节pH值为4.5至5.5,(6)分离产物三胍硝酸盐。
