Hazard Information

General Description

Colorless crystalline solid. Contact may cause severe irritation to skin, eyes, and mucous membranes. May be toxic by ingestion.

Reactivity Profile

Sulfuric acid fumes may form in fires [USCG, 1999]. Solid HYDROXYLAMINE SULFATE(10039-54-0) explodes when heated to 170°C., [Chem. Process 26:30(1963)]. Sodium ignites on contact with hydroxylamine. (Mellor, 1940, Vol. 8, 292.)

Air & Water Reactions

Water soluble.

Hazard

Irritant to tissue.

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.

Chemical Properties

Also hydroxylammonium sulfate, or HS, (NH2OH)2·H2S04 is colorless crystals that are soluble in water and slightly soluble in alcohol. The solution has a corrosive action on the skin. Used as a reducing agent, photographic developer, purification agent for aldehydes and ketones, chemical synthesis, textile chemical, oxidation inhibitor for fatty acids, catalyst, in biological and biochemical research, for making oximes for paints and varnishes, and rustproofing.

Physical properties

Colorless, crystalline solid; melts at 177°C (decomposes); very soluble in386 HYDROXYLAMINE HYDROCHLORIDE / HYDROXYLAMINE SULFATEpp-03-25-new dots.qxd 10/23/02 2:38 PM Page 386 water; slightly soluble in alcohol.

Uses

As reducing agent in photography; in synthetic and analytical chemistry; to purify aldehydes and ketones. As antioxidant for fatty acids and soaps. As dehairing agent for hides.

Uses

Hydroxylammonium sulfate is a reducing agent in photography; catalyst, swelling agent, and copolymerization inhibitor in polymerization processes; in chemical synthesis; as a textile chemieal; as an oxidation inhibitor; in making oximes for paints and varnishes; in rustproofing; in nondiscoloring short -stoppers for synthetic rubbers; for unhairing hides; in biological and biochemical research; as a purification agent for aldehydes and ketones; converts aldehydes and ketones to oximes and acid chlorides to hydroxamic acids.

Uses

Used as to purify aldehydes and ketones; reagent for mercury and silver detection in water; reducing agent.

Preparation

Hydroxylamine sulfate may be prepared by mixing stoichiometric amountsof hydroxylamine and sulfuric acid. It also may be prepared by electrolytical-ly reducing an aqueous solution of ammonium sulfate.

Flammability and Explosibility

Nonflammable

Purification Methods

Crystallise it from boiling water (1.6mL/g) by cooling to 0o.
