A process for producing high bulk density spheroidal nitroguanidine by fong a solution of from 2 to 9 weight percent of nitroguanidine, 0.5 to 2.0 weight percent of methylcellulose, and 0.5 to 2.0 weight percent of partially hydrolyzed poly(vinyl alcohol) in water at a temperature of from 50.degree. C. to 100.degree. C., and then cooling the solution at a rate of from I to 20.degree. C./minute until the solution temperature is less than 40.degree. C.

Method of producing high bulk density spheroidal nitroguanidine

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.

Method of producing triaminoguanidine nitrate

An explosive ternary nitrate mixture of ethylenediamine dinitrate, ammonium itrate, and potassium is prepared by mixing together approximately stoichiometric amounts of aqueous nitric acid, ethylenediamine, ammonia, and potassium hydroxide at a temperature of less than about 130.degree. C. The additions can be made simultaneously or sequentially in any order.
