Reactive Group:

Sulfonates, Phosphonates, and Thiophosphonates, Organic

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].

Heat of Combustion:

-9,500 Btu/lb= -5,300 Cal/g
