SULFURIC ACID Chemical Properties,Usage,Production

Chemical Properties viscous liquid General Description Thick fuming yellow liquid. Density 16.5 lb / gal. Very toxic by inhalation. Corrosive to metals and tissue, quickly causing severe burns. Used to make chemicals, dyes, explosives and in petroleum refining. Air & Water Reactions Fumes in air. Soluble in water; dissolution generates dangerous amounts of heat that can cause localized boiling and spattering of the acidic mixture and generate heavy fumes. During sulfonation of mononitrobenzene with fuming sulfuric acid, a leak from an internal cooling coil permitted water to enter the reaction tank. A violent eruption occurred due to the heat of solution [MCA Case History 944(1963)]. Reactivity Profile SULFURIC ACID reacts as a strong acid, as an oxidizing agent and as a dehydrating agent. Chars wood, sugar and many other organic materials on contact. The heat from these reactions may ignite the wood, sugar or organic matter. May react explosively with acetic acid, acetic anhydride, acetonitrile, acrolein, acrylic acid, acrylonitrile, allyl alcohol, allyl chloride, ammonium hydroxide, aniline, cresol, butyraldehyde, cumene, ethyl acetate, ethylene diamine, ethylene glycol, glyoxal, isoprene, isopropyl alcohol, methyl ethyl ketone, propylene oxide, pyridine, styrene, vinyl acetate; strong bases (sodium hydroxide, potassium hydroxide) or mineral acids (nitric acid, hydrochloric acid, hydrofluoric acid) [Lewis, 3rd ed., 1993, p. 1195]. Mixing in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: 2-aminoethanol, ammonium hydroxide (28%), chlorosulfonic acid, ethylenediamine, ethyleneimine, ethylene cyanohydrin, hydrochloric acid (36%), hydrofluoric acid (48.7%), isopropyl alcohol, nitric acid (70%), 2-nitropropane, propiolactone, propylene oxide, pyridine, styrene monomer, sodium hydroxide, sulfolane, vinyl acetate, vinylidene chloride [NFPA 1991]. Extremely hazardous in contact with carbides, bromates, chlorates, fulminates, picrates, and powdered metals. May induce violent polymerization in polymerizable organic compounds such as allyl chloride. Reacts exothermically with sodium hypochlorite to produce chlorine gas. Health Hazard Acid mist is irritating to eyes, nose and throat. Liquid causes severe burns of skin and eyes. Fire Hazard Special Hazards of Combustion Products: Toxic and irritating vapors are generated.
