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.
