Sulfolane (also tetramethylene sulfone, systematic name: 1λ 6-thiolane-1,1-dione) is an organosulfur compound, formally a cyclic sulfone, with the formula (C H 2) 4 S O 2. It is a colorless liquid commonly used in the chemical industry as a solvent for extractive distillation and chemical reactions.

Sulfolane | C4H8O2S | CID 31347 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.

Sulfolane is a polar aprotic solvent that may be used for the complete pyrolysis of cellulose without any polymerization or carbonization side reaction. Sulfolane, in combination with mesitylene, can be used as a solvent in the synthesis of …

Sulfolane is classified as a sulfone, a group of organosulfur compounds containing a sulfonyl functional group. The sulfonyl group is a sulfur atom doubly bonded to two oxygen atoms. The sulfur - oxygen double bond is highly polar, allowing for its high solubility in water, while the four carbon ring provides non-polar stability.

2025年1月27日 · Sulfolane (CAS 126-33-0) information, including chemical properties, structure, melting point, boiling point, density, formula, molecular weight, uses, prices, suppliers, SDS and more, available at Chemicalbook.

2024年10月30日 · Sulfolane is a highly water-soluble solvent commonly used for refining natural gas and petroleum and was found in contaminated groundwater and well water in North Pole, Alaska, near a petroleum refinery in 2009.

The solvent sulfolane (thiolane S,S-dioxide) is prepared by first reacting sulfur dioxide with butadiene to give sulfolene (a cyclic, unsaturated, five-membered ring sulfone), followed by hydrogenation to yield sulfolane.

2010年4月27日 · Sulfolane is used for removing aromatics from saturated hydrocarbons and in liquid–vapor extractions such as the purification of natural gas. Learn more about this molecule from CAS , the most authoritative and comprehensive source for chemical information.

2012年6月14日 · Sulfolane is a highly stable and attractive alternative to other more common dipolar aprotic solvents such as DMSO, DMF, DMAC, and NMP. Sulfolane is more toxic than the other solvents but has a very low skin penetration in comparison to that of the others.

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].
