Chemical compound
Sulfolane (also tetramethylene sulfone, systematic name: 1λ6-thiolane-1,1-dione) is an organosulfur compound, formally a cyclic sulfone, with the formula (CH2)4SO2. It is a colorless liquid commonly used in the chemical industry as a solvent for extractive distillation and chemical reactions. Sulfolane was originally developed by the Shell Oil Company in the 1960s as a solvent to purify butadiene.[1][2] Sulfolane is a polar aprotic solvent, and it is miscible with water.
