Sulfolane is Polar solvent with strong solubility and good selectivity. Most organic compounds and polymers can be soluble in or miscible with Sulfolane. Mainly used as an extractant for aromatic hydrocarbon extraction, polymer spinning or casting solvent, purification of natural Chemicalbook gas, synthetic gas, refinery gas, purification and desulfurization of synthetic gas, and as a solvent for rubber and plastics. In addition, it can also be used as a printing and dyeing assistant in the textile printing and dyeing industry, which can make colors bright and bright.
