*Antioxidant

PROPERTIES OF HYDROXYLAMMONIUM SULPHATE:
Chemical
At 120 °C, Hydroxylammonium Sulphate begins to decompose to sulfur trioxide, nitrous oxide, water, and ammonia:

2 (NH3OH)2SO4 → 2 SO3 + N2O + 2 NH3 + 5 H2O

Physical
Hydroxylammonium Sulphate is a white solid, soluble in water.

Availability
Hydroxylammonium Sulphate is sold by chemical suppliers.

Preparation
Hydroxylammonium Sulphate can be prepared by reducing acidified potassium nitrite (aka nitrous acid) with potassium bisulfite.

HNO2 + 2 KHSO3 → (KSO3)2NOH + H2O
2 (KSO3)2NOH + 4 H2O → (NH3OH)2SO4 + 2 K2SO4 + H2SO4

PREPARATION METHOD OF HYDROXYLAMMONIUM SULPHATE:
methylethylketone is reacted with sulfuric acid and ammonia to form methylethylketone oxime, which is then reacted with sulfuric acid to obtain hydroxylamine sulfate (crystalline form) and methylethylketone and ammonium sulfate by-products by hydrolysis.

Sodium nitrite and ammonium bisulfite are mixed and reacted, sulfur dioxide is introduced at a low temperature to make the reactant absorb hydroxylamine disulfonate, and then hydrolysis is carried out to produce Hydroxylammonium Sulphate.
Hydroxylammonium Sulphate can also be obtained by reacting sulfuric acid with nitrohydrocarbons.
