chemical properties colourless crystals
general description colorless oily liquid with a weak oily odor. solidifies (freezing point is 79°) and sinks on first contact with water, then mixes with water. f.
air & water reactions water soluble.
reactivity profile mixing sulfolane in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid and oleum [nfpa 1991]. with nitrating agents (nitronium tetrafluoroborate in sulfolane) very highly exothermic reactions are known to occur, [j. org. chem., 1978, 43, 4677].
health hazard very mildly irritating to the eyes.
fire hazard special hazards of combustion products: toxic, irritating gases may be generated in fires.
