Thionyl chloride Chemical Properties,Usage,Production

Chemical Properties Colorless to slightly yellow liquid General Description A colorless to yellow fuming liquid with a suffocating pungent odor. Boiling point 79°C. A lachrymator. Highly corrosive and toxic. Long-term inhalation of low concentrations or short-term inhalation of high concentrations has adverse health effects. Reactivity Profile Thionyl chloride reacts, potentially explosively, with dimethyl sulfoxide or dimethylformamide containing traces of iron or zinc [Spitulnik, M. J., Chem. Eng. News, 1977, 55(31), p. 31]. Undergoes violent reactions with bases (ammonia, sodium hydroxide, potassium hydroxide, amines), alkali metals (sodium, potassium), esters (ethyl acetate), toluene mixed with ethanol / water [Bretherick, 5th ed., 1995, p. 1325]. Has an expansion ratio from gas to liquid of nearly 1000:1. Hence may cause an explosion if heated while contained [MCA Case History No. 1808]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291]. Perchloric acid ignites on contact with sulfinyl chloride. (Bailar, 1973, Vol. 2, 1442). SOCl2 reacts with esters, such as ethyl acetate, forming toxic SO2 gas and water soluble/toxic acyl chlorides, catalyzed by Fe or Zn (Spagnuolo, C.J. et al. 1992. Chemical and Engineering News 70(22):2.). Health Hazard CORROSIVE and/or TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Fire will produce irritating, corrosive and/or toxic gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control or dilution water may cause pollution. Fire Hazard EXCEPT FOR ACETIC ANHYDRIDE (UN1715), THAT IS FLAMMABLE, some of these materials may burn, but none ignite readily. May ignite combustibles (wood, paper, oil, clothing, etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Flammable/toxic gases may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. Substance may be transported in a molten form.
