Benzenesulfonyl chloride Usage And Synthesis |
Chemical Properties | colourless oily liquid |
Usage | Intermediates of Liquid Crystals |
General Description | A colorless to slightly yellow solid that melts at approximately 40°F. Very irritating to skin, eyes and mucous membranes. May emit toxic fumes when heated to high temperatures. Used to make dyes and other chemicals. |
Air & Water Reactions | Insoluble and stable in cold water [Merck]. Decomposes in hot water to produce corrosive and toxic hydrochloric acid and benzenesulfonic acid. Rate of reaction decreases as temperature decreases. |
Reactivity Profile | Benzenesulfonyl chloride is incompatible with strong oxidizing agents and bases, including amines. Corrodes metals in the presence of water due to slow formation of hydrochloric acid and benzenesulfonic acid [USCG, 1999]. 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]. |
Health Hazard | May be fatal if inhaled, swallowed or absorbed through skin. Contact may cause skin and eye burns. Irritating to eyes, skin and mucous membranes. INGESTION: May cause abdominal spasm and vomiting. |
