Product Application of Sulfolane CAS#126-33-0

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

In addition, Chemicalbook can also be used in the textile printing and dyeing industry as a printing and dyeing auxiliary to make colors bright and bright. Sulfolane solvent has high solubility for aromatic hydrocarbons, 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 hydrocarbon in the world. Extraction technology.
