Method of making hydroxyamine and products therefrom

Abstract

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.
