In case of spills, mop up with sand - do not add water. Reacts with most metals to yield (flammable) hydrogen gas. Incompatible with strong bases, carbonates, water, combustible materials, strong oxidizing agents, most metals, organic materials, sulfides, cyanides, carbides. | CAS DataBase Reference | 7790-94-5(CAS DataBase Reference) | EPA Substance Registry System | Chlorosulfuric acid(7790-94-5) |
| Chlorosulfonic acid Usage And Synthesis |
Chemical Properties | colourless to light yellow liquid | Usage | Chlorosulfuric Acid is used in the preparation of benzothiazepinylphosphonate bile acid transporter inhibitor. Also used in the preparation ofsulfated guar gum for potential use as an antioxidant. | General Description | A colorless to yellow colored fuming liquid with a pungent odor. Density 14.7 lb / gal. Causes severe burns. Very toxic by inhalation. Corrosive to metals. | Reactivity Profile | Chlorosulfonic acid is a strong oxidizing acid. Reacts violently with water, strong mineral acids and bases, alcohols, finely dispersed organic matter. Dangerously incompatible with combustible materials, nitrates, chlorates, metallic powders, carbides, picrates, and fulminates. Undergoes possibly violent reactions with acetic acid, acetic anhydride, acetonitrile, acrolein, acrylic acid, acrylonitrile, alkali, allyl alcohol, allyl chloride, ammonium hydroxide, aniline, butyraldehyde, cresol, cumene, diethyleneglycol methyl ether, diisopropyl ether, diphenyl ether, ethyl acetate, ethyl acrylate, ethylene chlorohydrin, ethylenediamine, ethylene glycol, glyoxal, hydrocarbons (hexane, heptane), hydrogen peroxide, isoprene, powdered metals, methyl ethyl ketone, propylene oxide, vinyl acetate. When heated to decomposition, Chlorosulfonic acid emits toxic fumes of hydrogen chloride and oxides of sulfur [Sax, 9th ed., 1996, p. 831]. Reaction with phosphorus accelerates out of control and culminates in an explosion [Heumann, K. et al., Ber., 1882, 15, p. 417]. Mixing chlorosulfuric acid and 98% sulfuric acid may evolve HCl [Subref: Anon, Loss Prev. Bull. 1977, (013), 2-3]. | Health Hazard | INHALATION: vapor extremely irritating to lungs and mucous membranes. Vapor has such a sharp and pentrating odor that inhalation of severely toxic quantities is unlikely unless it is impossible to escape the fumes. CONTACT WITH EYES OR SKIN: liquid acid will severely burn body tissue. |
