Safety Information
Antimony trichloride Usage And Synthesis
  • Chemical PropertiesColourless Crystal Or Flakes,fuming in moist air.
  • Chemical PropertiesAntimony trichloride is a noncombustible, clear, colorless, crystalline solid. Acrid, pungent odor.
  • UsesUsed in the chemical microscopy of drugs.
  • UsesBronzing iron, especially gun barrels; mordant for patent leather and in dyeing; coloring zinc black; manufacture of lakes, particularly from dye woods; furniture polishes.
  • DefinitionChEBI: An inorganic chloride salt with formula SbCl3. It is used as a reagent for detecting vitamin A and related carotenoids, reacting with the carotenoid to form a blue complex that can be measured by colorimetry (the Carr-Price test). Solu ions of antimony trichloride were formerly used for dissolving and removing horn stubs from calves and goats.
  • DefinitionA white deliquescent solid, formerly known as butter of antimony. It is prepared by direct combination of antimony and chlorine. It is readily hydrolyzed by cold water to form a white precipitate of antimony(III) chloride oxide (antimonyl chloride, SbOCl): SbCl3 + H2O = SbOCl + 2HCl.
  • General DescriptionAntimony trichloride is a colorless crystalline solid. Antimony trichloride is shipped as a solid or liquid solution. Antimony trichloride is decomposed slowly by water to hydrochloric acid and antimony oxychloride. Antimony oxychloride is soluble in hydrochloric acid but insoluble in water. Antimony trichloride is corrosive to metals and tissue.
  • Air & Water ReactionsFumes in air to form hydrochloric acid [Merck 11th ed. 1989]. Decomposed by water to form hydrochloric acid and antimony oxychloride.
  • Reactivity ProfileAcidic salts, such as ANTIMONY TRICHLORIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
  • Hazard Corrosive liquid or solid. Very irritating to eyes, skin.
  • Health HazardTOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
  • Fire HazardNon-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.
  • Safety ProfileModerately toxic by ingestion. Human pulmonary system effects by inhalation. Corrosive by vigorous reaction with moisture, generating heat and hydrogen chloride gas (a strong irritant), whch can cause pulmonary edema when inhaled. Systemic effects can be caused by the antimony. See also ANTIMONY COMPOUNDS. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits very toxic fumes of chlorine and antimony. It can react violently with aluminum, potassium, sodmm.
  • Potential ExposureIt is used to make antimony salts and drugs; to fireproof textiles; and as a catalyst in many organic reactions; as a reagent for chloral, aromatic hydrocarbons, vitamin A, and for drug identification.
  • ShippingUN1733 Antimony trichloride, Hazard class: 8; Labels: 8-Corrosive material.
  • Purification MethodsDry the trichloride over P2O5 or by mixing it with toluene or xylene and distilling (water is carried off with the organic solvent), then distil it twice under dry nitrogen at 50mm, and sublime it twice in a vacuum into ampoules and seal. It can be crystallised from CS2 and is deliquescent. It fumes in moist air and is decomposed by H2O with precipitation of the basic chloride, but forms a clear solution in dilute HCl.
  • IncompatibilitiesDecomposes in water, forming hydrochloric acid and antimony oxychloride. Reacts violently with strong bases; ammonia, alkali metals; aluminum, potassium, sodium. Forms explosive mixture with perchloric acid when hot. Reacts with air forming hydrochloric acid. Attacks metals in the presence of moisture, forming explosive hydrogen gas.
  • Waste DisposalConsult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
