Hydroxylimine Hydrochloride HCL

Hydroxylimine Hydrochloride HCL and its salts are commonly used as reducing agents in myriad organic and inorganic reactions. They can also act as antioxidants for fatty acids.

 

Hydroxylamine is an inorganic compound with the formula NH2OH. The pure material is a white, unstable crystalline, hygroscopic compound.[4] However, hydroxylamine is almost always provided and used as an aqueous solution. It is used to prepare oximes, an important functional group. It is also an intermediate in biological nitrification. In biological nitrification, the oxidation of NH3 to hydroxylamine is mediated by the enzyme ammonia monooxygenase (AMO).[5] Hydroxylamine oxidoreductase (HAO) further oxidizes hydroxylamine to nitrite.[6

 

NH2OH can  produced via several routes. The main route is via the Raschig process: aqueous ammonium nitrite is reduced by HSO3 and SO2 at 0 °C to yield a hydroxylamido-N,N-disulfonate anion:

NH4NO2 + 2 SO2 + NH3 + H2O → 2 NH4+ + N(OH)(OSO2)22−

This anion  then hydrolyzed to give (NH3OH)2SO4:

N(OH)(OSO2)22− + H2O → NH(OH)(OSO2) + HSO4
2 NH(OH)(OSO2) + 2 H2O → (NH
3OH)
2SO

+ SO2−

Solid NH2OH can  collected by treatment with liquid ammonia. Ammonium sulfate, (NH

, a side-product insoluble in liquid ammonia, is removed by filtration; the liquid ammonia  evaporated to give the desired product.[4]

The net reaction is:

(NH3OH)Cl + NaOBu → NH2OH + NaCl + BuOH[4]

Julius Tafel discovered that hydroxylamine hydrochloride or sulfate salts can be produced by electrolytic reduction of nitric acid with HCl or H2SO4 respectively:[10][11]
