A process for preparing triaminoguanidine nitrate from relatively impure 90-99 percentcommercial 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.
