Abstract
Solid hydroxylammonium sulfate is reacted with an alcohol solution of an alkali metal hydroxide or alkoxide to produce an alcoholic hydroxylamine liquid phase and a sulfate-containing solid phase. The liquid phase may be used for further reactions such as oxidations, hydroxamic acid production or neutralization to other hydroxylammonium salts. The different bases behave differently with regard to suitable and preferable solvents and temperatures.
