Claims14
A method for preparing hydroxylamine acid salts which comprises:
- preparing a slurry of hydroxylamine sulfate in an alcohol at a temperature not in excess of about 65.degree. C.;
- high-shear mixing ammonia with said slurry to form a hydroxylamine-alcohol solution and ammonium sulfate while maintaining the temperature of said slurry at or below 65.degree. C.;
- removing ammonium sulfate;
- agitating said solution;
- admixing an acid selected from the group consisting of nitric acid and perchloric acid with said solution at a temperature not in excess of about 50.degree. C. to form said hydroxylamine acid salt;
- and
- recovering said hydroxylamine acid salt.
