Details
Sulfolane, also known as 1,1 - dioxide tetrahydrothiophene. High-purity sulfolane at room temperature is colorless odorless solid, melting point is 27.8 ℃, industrial products, mostly pale yellow liquid, has high dissolved ability, good selectivity solvents. It can be in any rate of water, can be soluble in aromatic hydrocarbons and alcohols, while the dissolution for paraffin and alkene has little change, the thermal stability is high for heat, acid and alkali. At room temperature will not have reaction with acid, alkali, dienes, sulfur, alcohol etc, and not have decomposition and polymerization, When the temperature is 240 ℃ above, partly disassembled and released SO2.
