Sulfolane,

also known as 1,1 - dioxide tetrahydrothiophene.High-purity sulfolane at room temperature is a , melting point 27.8, industrial products, mostly pale yellow liquid, is dissolvedability, good selectivity and more effective polar solvents. It canbe in any ratio of water miscible, soluble in aromatic hydrocarbonsand alcohols, while the dissolution of paraffin and olefin littleto heat, acid, alkali and high stability. Room temperature withacid, alkali, dienes, sulfur, alcohol does not react, ordecomposition and polymerization, 240 above, some decompositionrelease SO2.
