化学的特性
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.

使用
Hydroxylamine sulfate may be used to prepare highly sensitive cellulose tape, used for the detection of formaldehyde gas. It may be used in the quantitative determination of perchlorate in biological fluids by spectrophotometric methods .
-
製造方法
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.
-
一般的な説明

反応プロフィール
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.)

危険性
Irritant to tissue.
-
健康ハザード
Inhalation of dust or ingestion may cause systemic poisoning characterized by cyanosis, methemoglobinemia, convulsions, and coma. Contact with eyes or skin causes irritation.

火災危険
Special Hazards of Combustion Products: Sulfuric acid fumes may form in fires.
-
安全性プロファイル
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 SOx and NOx. See also AMINES and SULFATES.
-
純化方法
Crystallise it from boiling water (1.6mL/g) by cooling to 0o.
