Safety Information
ANTIMONY(V) CHLORIDE Usage And Synthesis
  • Chemical Propertiescolourless to light yellow oily liquid
  • Chemical PropertiesAntimony pentachloride is a noncombustible, colorless to reddish-yellow oily liquid with an offensive odor.
  • Physical propertiesAntimony pentachloride is prepared by passing chlorine gas into molten antimony trichloride:
    SbCl3 + Cl2 →SbCl5
    or by the reaction of the element with excess chlorine:
    2 Sb + 5 Cl2 → 2 SbCl5.
  • UsesAs catalyst when replacing a fluorine substituent with chlorine in organic compounds.
  • General DescriptionA reddish-yellow fuming liquid with a pungent odor. Fumes are irritating to the eyes and mucous membranes. Solidifies at 37°F. Corrosive to metals and tissue. Used to make other chemicals, and in chemical analysis.
  • Air & Water ReactionsFumes in air to form hydrochloric acid. Reacts with water to yield heat and antimony pentaoxide (Sb2O5) and hydrochloric acid [Merck 11th ed. 1989].
  • Reactivity ProfileAcidic salts, such as ANTIMONY PENTACHLORIDE, 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.
  • HazardCorrosive, fumes in moist air, reacts strongly with organics.
  • Health HazardInhalation causes irritation of nose and throat. Contact of liquid with eyes or skin causes severe burns. Ingestion causes vomiting and severe burns of mouth and stomach. Overexposure by any route can cause bloody stools, slow pulse, low blood pressure, coma, convulsions, cardiac arrest.
  • Fire HazardBehavior in Fire: Irritating fumes of hydrogen chloride given off when water or foam is used to extinguish adjacent fire.
  • Safety ProfilePoison by ingestion. Corrosive. Mutation data reported. See ANTIMONY COMPOUNDS and ANTIMONYPII) CHLORIDE. When heated to decomposition it emits very toxic fumes of Cland Sb.
  • Potential ExposureIt is used in dyeing, coloring metals and in many organic chemical reactions as a catalyst.
  • ShippingUN1730 (liquid) Antimony pentachloride, liquid, Hazard class: 8; Labels: 8-Corrosive material. UN1731 (solution) Antimony pentachloride, solutions, Hazard class: 8; Labels: 8-Corrosive material.
  • IncompatibilitiesDecomposes on contact with heat, acids, alkalis, ammonia, water or other forms of moisture producing fumes of hydrogen chloride and antimony. Decomposes above 77 C forming chlorine and antimony trichloride. Attacks many metals in the presence of moisture forming explosive hydrogen gas. Reacts with air forming corrosive vapors.
  • Waste DisposalEncapsulate and transfer to an approve landfill. If chemically treated and neutralized, the chemical is amenable to biological treatment at municipal sewage treatment plant. Consult 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.
