HYDROXYLAMINE HYDROCHLORIDE FOR SYNTHESIS
Hydroxylamine hydrochloride can be prepared technically by the electrolytic reduction of nitric acid1 and by the action of sodium bisulfite on sodium nitrite.
Hydroxylamine hydrochloride is a monomoamine oxidase inhibitor. It is used to prepare oximes and hydroxmic acids in organic synthesis. It acts as a copolymerization inhibitor. It can be used to remove bromine and polybromide from a solution during extraction of lignin from lignocellulosic biomass.
Hydroxylamine is used as a reducing agent in photography, in synthetic and analytical chemistry, to purify aldehydes and ketones, as an antioxidant for fatty acids and soaps, and as a dehairing agent for hides. In addition, hydroxylamine is used in the production of cyclohexanone oxime or caprolactam.
Hydroxylamine may be prepared by several methods; of current technical importance are the hydrolysis of nitroalkanes (RCH2NO2) and the catalytic hydrogenation of nitric oxide (NO). Hydroxylamine, NH2OH, may be thought of as being derived from ammonia by
