Properties:
Chemical Properties: white crystals or powder
General Description: Colorless crystalline solid. Contact may cause severe irritation to skin, eyes, and mucous membranes. May be toxic by ingestion.

Air & Water Reactions:

Water soluble.

Reactivity Profile: Sulfuric acid fumes may form in fires [USCG, 1999]. Solid Hydroxylamine sulfate explodes when heated to 170°C., [Chem. Process 26:30(1963)]. Sodium ignites on contact with hydroxylamine. (Mellor, 1940, Vol. 8, 292.)
Health Hazard: Inhalation of dust or ingestion may cause systemic poisoning characterized by cyanosis, methemoglobinemia, convulsions, and coma. Contact with eyes or skin causes irritation.
Fire Hazard: Special Hazards of Combustion Products: Sulfuric acid fumes may form in fires.
   

Stability

Stable, but may be an explosion hazard - do not heat. It may decompose explosively in the presence of alkalis. It is air sensitive & hygroscopic. Incompatible with copper, copper alloys, strong oxidizing agents, strong bases, nitrites.
   

Synthesis:

Hydroxylammonium sulfate can be obtained by the acid-base reaction of hydroxylamine with sulfuric acid:
2NH2OH (aq) + H2SO4 (aq) – (NH3OH)2SO4 (aq).
   
Applications:
  • Hydroxylammonium sulfate is used in organic synthesis to convert aldehydes and ketones to oximes, carboxylic acids and their derivatives (e.g. esters) to hydroxamic acids, isocyanates to N-hydroxyureas and nitriles to amidoximes. Hydroxylammonium sulfate is also used to generate hydroxylamine-O-sulfonic acid from oleum or chlorosulfuric acid.
  • Hydroxylammonium sulfate is used in the production of anti-skinning agents, pharmaceuticals, rubber, textiles, plastics and detergents.
  • It is a radical scavenger that terminates radical polymerization reactions and serves as an antioxidant in natural rubber.
  • (NH3OH)2SO4 is a starting material for some insecticides, herbicides and growth regulators.
  • It is used in photography as a stabilizer for color developers and as an additive in photographic emulsions in color film.
