Hydroxylamine hydrochloride Usage And Synthesis

Chemical Properties

White crystals

Uses

Organic synthesis, photographic developer, medicine, controlled reduction reactions, nondiscoloring short-stopper for synthetic rubbers, antioxidant for fatty acids.

General Description

Colorless or off-white crystalline solid. pH (0.1 molar aqueous solution) 3.4. pH (0.2 molar aqueous solution) 3.2.

Air & Water Reactions

Hygroscopic. Sensitive to prolonged exposure to air. Water soluble. Reacts slowly with water.

Reactivity Profile

A powerful reducing agent. Reacts with bases and oxidizing agents.

Hazard

Toxic by ingestion, strong irritant to tissue.

Fire Hazard

Flash point data for Hydroxylamine hydrochloride are not available; however, Hydroxylamine hydrochloride is probably combustible.

Contact allergens

Hydroxylamine and its salts are used in various branches of industry, as reducing agents in color film developers or as reagents in laboratories.

Purification Methods

Crystallise the salt from aqueous75% ethanol or boiling methanol, and dry it under vacuum over CaSO4 or P2O5. It has also been dissolved in a minimum of water and saturated with HCl; after three such crystallisations, it is dried under a vacuum over CaCl2 and NaOH. Its solubility at 20o is 85% in H2O, 6% in EtOH and 12% in MeOH. [Hurd Inorg Synth I 87 1939, Semon in Org Synth Coll Vol I 318 1941.]
