Antimony(V) chloride (CAS NO.7647-18-9) is used for high-purity analytical reagents, catalysts, and also for preparation of high purity antimony.
Antimony(V) chloride (CAS NO.7647-18-9) is prepared by passing chlorine gas into molten antimony trichloride:
SbCl3 + Cl2 → SbCl5

DOT Classification: 8; Label: Corrosive
1.General Description :A 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.
2.Air & Water Reactions: Fumes in air to form hydrochloric acid. Reacts with water to yield heat and antimony pentaoxide (Sb2O5) and hydrochloric acid 3.Reactivity Profile: Acidic 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.
4.Health Hazard :Inhalation 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.
5.Fire Hazard :Behavior in Fire: Irritating fumes of hydrogen chloride given off when water or foam is used to extinguish adjacent fire.
