General Description
Antimony trifluoride solution is the white to gray crystalline solid dissolved in water. ANTIMONY TRIFLUORIDE, SOLUTION(7783-56-4) is corrosive to metals and tissue. ANTIMONY TRIFLUORIDE, SOLUTION(7783-56-4) is used in ceramics and to make other chemicals.
Reactivity Profile
ANTIMONY TRIFLUORIDE is a colorless, solid compound, toxic and corrosive. When heated to decomposition, ANTIMONY TRIFLUORIDE, SOLUTION emits very toxic fumes of fluoride and metallic antimony [Lewis, 3rd ed., 1993, p. 83].
Air & Water Reactions
Water slowly hydrolyzes antimony fluoride to form antimony (III) oxide. The dry powdered oxide ignites on heating in air [Mellor Vol. 9 425.1939].
Hazard
Strong irritant to eyes and skin.
Health Hazard
TOXIC; 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.
Potential Exposure
It is used in dyeing; to make porcelain
and pottery; and as a fluorinating agent.
Fire Hazard
Non-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.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and
CPR if heart action has stopped. Transfer promptly to a
medical facility. When this chemical has been swallowed,
get medical attention. If victim is conscious, administer
water or milk. Do not induce vomiting. Medical observation
is recommended for 24 to 48 hours after breathing
overexposure, as pulmonary edema may be delayed.
As first aid for pulmonary edema, a doctor or authorized
paramedic may consider administering a drug or other
inhalation therapy.

Waste Disposal
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.
Uses
To 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.
storage
Color Code—Blue: Health Hazard/Poison: Store ina secure poison location. Prior to working with this chemicalyou should be trained on its proper handling and storage.Store in tightly closed containers in a cool, well-ventilatedarea away from heat.
Purification Methods
It 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].
