Abstract

A method of producing triaminoguanidine nitrate wherein a source of free nitrate ions is provided in an aqueous medium during reaction of guanidine nitrate and hydrazine to increase the yield of triaminoguanidine nitrate.

Claims

1. A method of producing triaminoguanidine nitrate, said method comprising the steps of:

forming a source of free nitrate ions within an aqueous medium, and

reacting guanidine nitrate with hydrazine in said aqueous medium to produce

2. The method of claim 1 wherein said reacting step comprises:

heating said aqueous medium and said reactants to a temperature in the range of about 80°

C to 104°

C for a period of about one hour, and

subsequently cooling said aqueous medium and said reactants to about

3. The method of claim 1 wherein said forming step consists of adding up to about 50 parts by weight of ammonium nitrate to about 250 parts by weight

4. The method of claim 1 wherein said forming step consists of adding up to about 55 parts by weight of 70% nitric acid to about 250 parts by weight

5. The method of claim 1 wherein said forming step consists of adding up to about 50 parts by weight of hydrazine nitrate to about 250 parts by weight of said aqueous medium.
