Uses

Hydroxylamine sulfate (CAS NO.10039-54-0) is used in organic synthesis. It is also used to generate hydroxylamine-O-sulfonic acid from oleum or chlorosulfuric acid. It is used in photography as a stabiliser for colour developers and as an additive in photographic emulsions in colour film. 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.

Production

Hydroxylammonium sulfate can be obtained by the acid-base reaction of hydroxylamine with sulfuric acid:
2NH₂OH(aq) + H₂SO₄(aq) → (NH₃OH)₂SO₄(aq)

HazardClass: 8
PackingGroup: III
HS Code: 28251000
Poison by skin contact and intraperitoneal routes. Mutation data reported. A corrosive irritant to skin, eyes, and mucous membranes. Moderately explosive when exposed to heat or by chemical reaction. In the presence of alkalies at elevated temperatures, free hydroxylamine is liberated and may decompose explosively. When heated to decomposition it emits toxic fumes of SO_x and NO_x. See also AMINES and SULFATES.

Specification

Hydroxylamine sulfate (CAS NO.10039-54-0) is also named as Bis(hydroxylamine) sulfate ; Hydroxylamine neutral sulfate ; Hydroxylamine sulfate (2:1) ; Hydroxylamine, sulfate ; Oxammonium sulfate . Hydroxylamine sulfate (CAS NO.10039-54-0) is white crystals or powder. It is water soluble. Hydroxylamine sulfate may decompose explosively in the presence of alkalies. Contact may cause severe irritation to skin, eyes, and mucous membranes. It may be toxic by ingestion. Sulfuric acid fumes may form in fires. Solid Hydroxylamine sulfate explodes when heated to 170 °C. Sodium ignites on contact with hydroxylamine. 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.
