Product Description
Sulfolane Basic information
2,3,4,5-TETRAHYDROTHIOP HENE-1,1-DIOXIDE;LABOTEST-BBLT00239038;1,1-Dioxidetetrahydrothiofuran;1,1-dioxidetetrahydrothiofChemicalbookuran;1,1-Dioxidetetrahydrothioph ene;Thioxyclopentane-1,1-dioxide;SULFOLANE,STANDARDFORGC;TETRAHYDROTHIOPH ENE1,1-DIOXIDESulfolane is widely used as an industrial solvent, especially in the extraction of aromatic hydrocarbons from hydrocarbon mixtures and to purify natural gas. The first large scale commercial use of sulfolane, the sulfinol process, was first implemented by Shell Oil Company in March 1964 at the Person gas plant near Karnes City, Texas. The sulfinol process purifies natural gas by removing H2S, CO2, COS and mercaptans from natural gas with a mixture of alkanolamine and sulfolane.Sulfolane is the most common commercially available sulfone solvent. The solvent, also known as tetrahydrothioph ene-1,1-dioxide, is a colorless, highly polar liquid consisting of a fully hydrogenated five-member sulfur-carbon heterocyclic thioph ene ring. The solvent is available as both anhydrous sulfolane and as sulfolane containing 3 wt% deionized water. Sulfolane is used as a reaction medium, as a solvent for a wide variety of organic chemicals and polymers, and as an extraction solvent.Sulfolane is a very high boiling point, colorless liquid with a very high viscosity (10.3 centipoises) and medium surface tension value (35.5 dynes/cm).Sulfolane is miscible with water and many organic solvents.Sulfolane is used to separate aromatic hydrocarbons from aliphatic hydrocarbons. The extraction process first developed by Shell Oil in 1959 and which is referred to as the "Sulfolane" process is used worldwide. The solvency of sulfolane for certain fatty acids and fatty acid esters is the basis for upgrading animal and vegetable fatty acids used in food products, paints, plastics, resins, and soaps.Sulfolane is used to remove acidic components like hydrogen sulfide and carbon dioxide from gas feed stocks. Sulfolane is used as a polymerization solvent for the production of polysulfones, polysiloxanes, polyphenylene ethers, and other polymers. Sulfolane is said to increase the reaction rates, afford easier polymer purification, and improved thermal stability. Sulfolane is a solvent for dissolving a variety of polymers for use in the fiberspinning process.Cellulose and cellulose ester polymers can be plasticized with sulfolane to give improved flexibility and other physical property improvements. Other application areas that have used sulfolane include electronic and electrical uses, textile dye uses, curing of polysulfide sealant, and as a catalyst in certain synthetic reactions.Product details
