7783-18-8 Usage

Air & Water Reactions

Hygroscopic. Very soluble in water.

Description

Ammonium thiosulfate is an inorganic compound. It is white crystalline solid with ammonia odor, readily soluble in water, slightly soluble in acetone and insoluble in ethanol and diethyl ether. And Ammonium thiosulfate is used in photographic fixer. It is a so-called rapid fixer, acting more quickly than sodium thiosulfate fixers. Fixation involves these chemical reactions (illustrated for silver bromide). Ammonium thiosulfate is also used for leaching of gold and silver. It works with presence of copper as a catalyst here. This process is a nontoxic alternative gold cyanidation. Ammonium thiosulfate can be used as a fertilizer. As suggested by some research studies it can be used as an additive to coal-waste mixtures to reduce formation of very dangerous dioxins and furans.
Methods of Manufacturing
Direct reaction of ammonium sulfite with sulfur. Besides,the ATS process, sulfur dioxide is absorbed from incinerated Claus tail gas in aqueous ammonia to produce ammonium sulfate and ammonium bisulfite in solution. The solution passes to a converter where it flows countercurrent to hydrogen sulfide. Ammonium thiosulfate forms /in solution and/ is concentrated to 60 wt%.

General Description

AMMONIUM THIOSULFATE is a white crystalline solid. AMMONIUM THIOSULFATE is very soluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. AMMONIUM THIOSULFATE is used in photography, in chemical analysis, and for many other uses.

Uses

To clean "white" metal; in photography; in lubricants for metal cold-working.

Chemical Properties

white or colourless crystals

Health Hazard

Inhalation of dust may irritate respiratory system. Ingestion could be harmful. Contact with eyes or skin may cause irritation.

Reactivity Profile

AMMONIUM THIOSULFATE is sensitive to heat. AMMONIUM THIOSULFATE is incompatible with magnesium and aluminum powder. Mixtures with sodium chlorate can cause an exothermic reaction which can then decompose explosively. . Reacts with strong oxidizers such as chlorates, nitrates, and nitrites to release toxic ammonia, hydrogen sulfide, and sulfur trioxide gases. Will not polymerize. Ammonia, hydrogen sulfide, and oxides of nitrogen and oxides of sulfur may form in fires [USCG, 1999].

Toxicity

Ammonium thiosulfate exists as colorless, monoclinic or white crystals with ammonia like odor. It is very soluble in cold water; slightly soluble in acetone and insoluble in alcohol and ether. It is used to clean white metal; in lubricants for metal cold working, as an analytical reagent; fungicide, reducing agent; brightener in silver plating bath, and in hair waving preparations; fog screens, and cleaning compounds for zinc base die cast metals and it is used as a desiccant and defoliant in crop bearing plants. Inhalation of dust may irritate respiratory system. Contact with eyes or skin may cause irritation. Ingestion may be harmful.

Fire Hazard

Special Hazards of Combustion Products: Toxic ammonia, hydrogen sulfide, and oxides of nitrogen and sulfur may form in fires.
