Antimony trifluoride Usage And Synthesis
Chemical Propertieswhite to grey crystalline powder
Chemical PropertiesAntimony trifluoride is a noncombustible, odorless, white to gray crystalline solid.
UsesTo catalyze fluorinations by HF, manufacture of chlorofluorides, in dyeing, usually in form of double salts, e.g., antimony sodium fluoride or antimony fluoride and ammonium sulfate double salt, manufacture of pottery and porcelains.
UsesAntimony(III) fluoride is used as a reagent in inorganic and organofluorine chemistry. It acts as a fluorination reagent and electroplating agent. Further, it is used in the preparation of dye, pottery, porcelains, ceramic enamels and glazes. It is utilized in the preparation of Freon.
General DescriptionAntimony trifluoride solution is the white to gray crystalline solid dissolved in water. Antimony trifluoride is corrosive to metals and tissue. Antimony trifluoride is used in ceramics and to make other chemicals.
Air & Water ReactionsWater slowly hydrolyzes antimony fluoride to form antimony (III) oxide. The dry powdered oxide ignites on heating in air [Mellor Vol. 9 425.1939].
Reactivity ProfileANTIMONY TRIFLUORIDE is a colorless, solid compound, toxic and corrosive. When heated to decomposition, Antimony trifluoride emits very toxic fumes of fluoride and metallic antimony [Lewis, 3rd ed., 1993, p. 83].
HazardStrong irritant to eyes and 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 ProfilePoison by subcutaneous route. Corrosive to skin and eyes. See also FLUORIDES and ANTIMONY COMPOUNDS. When heated to decomposition it emits very toxic fumes of Fand Sb
Potential ExposureIt is used in dyeing; to make porcelain and pottery; and as a fluorinating agent.
ShippingUN1549 Antimony compounds, inorganic, solid, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
Purification MethodsIt crystallises from MeOH to remove oxide and oxyfluoride, then it is sublimed under vacuum in an aluminium cup on to a water-cooled copper condenser. Its solubility is 443g/100g in H2O at 20o and 562g/100g in H2O at 30o with partial hydrolysis. [Woolf J Chem Soc 279 1955, Kwasnik in Handbook of Preparative Inorganic Chem (Ed. Brauer) Academic Press Vol I p 199 1963].
IncompatibilitiesHot perchloric acid.
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.
