Henry's Law constant = 4.8X10-6 atm-cu m/mole (est)

Experimental Properties:

HIGHLY POLAR CMPD WITH OUTSTANDING SOLVENT PROPERTIES|Heat of solution = -22 Btu/lg = -12 Cal/g|Heat of fusion: 11.44 kJ/kg; dielectric constant: 43.3|Hydroxyl radical reaction rate constant = 1.3X10-11 cu cm/molecule-sec at 25 deg (est)

Air and Water Reactions:

Water soluble.

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
