Product Application of Sulfolane 99.5% CAS#126-33-0

A polar solvent with strong solubility and good selectivity. Most organic compounds and polymers can be dissolved in sulfolane or miscible with it. It is mainly used as an extractant for aromatic extraction, a solvent for polymer spinning or casting, purification of natural gas and synthesis gas, refinery gas, purification and desulfurization of synthesis gas, and as a solvent for rubber and plastics.

In addition, it can also be used in the textile printing and dyeing industry as a printing and dyeing auxiliary to make the color bright and shiny. Sulfolane solvent has high solubility for aromatics, good selectivity, good thermal stability, low vapor pressure, low toxicity and no corrosion to carbon steel. Therefore, sulfolane extraction technology has become the most widely used aromatic extraction technology in the world.
