An energetic binder system useful for making TPE-LOVA propellants and energetic composites comprises at least one thermoplastic elastomer, at least one plasticizer, and nitrocellulose.

Energetic binder and thermoplastic elastomer-based low vulnerability

The present invention concerns a method for making energetic oxidizer salts and solutions thereof, and in particular relates to processes for making aqueous solutions of hydroxylammonium nitrate in high purity suitable for use in making liquid gun propellants. The present alcohol-free process yields high purity alcohol-free hydroxylammonium nitrate by neutralizing an aqueous nitric acid solution (20-70% wt./wt.) with an alcohol-free aqueous hydroxylamine solution at temperatures ranging from above -50.degree. C. to substantially less than ambient (20.degree. C.) to produce the desired alcohol-free aqueous hydroxylammonium nitrate solution in a usable concentration and in high purity. The process is economical, environmentally acceptable, and facile.

Method of making hydroxyamine and products therefrom

The present invention pertains to a method for making energetic oxidizer salts and solutions thereof, and in particular relates to processes for making aqueous solutions of hydroxylammonium nitrate in high purity suitable for use in making liquid gun propellants. The present alcohol-free process yields high purity alcohol-free hydroxylammonium nitrate in a simple chemical neutralization reaction by combining an aqueous nitric acid solution 120 to 70 wt. %) with an alcohol-free aqueous hydroxylamine solution at temperatures ranging from about -50.degree. C. to above ambient to produce the desired alcohol-free aqueous hydroxylammonium nitrate solution in a usable concentration and in high purity. The process is economical, environmentally acceptable, and facile.

Process for making high purity hydroxylammonium nitrate

Cyanogen is prepared from glyoxime by reaction with acetic anhydride to form N,N'-diacetoxyglyoxime which is then pyrolyzed to cyanogen.
