Tetramethylene Sulfone

Tetramethylene Sulfone is a colorless oily liquid, Selective solvent for liquid-vapor extractions ,widely used as an industrial solvent, especially in the extraction of aromatic hydrocarbons from hydrocarbon mixtures and to purify natural gas. also used in lithium-ion batteries.

CAS No.: 126-33-0

Product Name: Tetramethylene Sulfone

Synonyms: Sulfolane; Tetrahydrothiophene 1,1-dioxide

Molecular Formula: C4H8O2S

MW: 120.17

Properties：

Sulfolane is a colorless and tasteless soild at room temperature, melted at 27.8℃.The most industrial products are colourless and light yellow liquid. Sulfolane has high solubility property and selectivity.Sulfolane is solubled in water with arbitrary ratio,also solubled in aromatics and alcohol easily,but solubled in paraffin and olefin hydrcarbon little.Sulfolane has high stability with hot acid and alkali.It doen’s react with acid,alkali, sulfur,alcohol at room temperature,also doen’s decompose and polymerize.When the temperature is higher than 240℃, the sulfolane will decompose SO2.Sulfolane has stable chemical property,it will not appear polyreaction and decomposition under common condition with the existence of acid and alkali.
