Used as a gas chromatography stationary solution and analytical reagent, also used in organic synthesis
Polar solvent with strong solubility and selectivity. Most organic compounds and polymers are soluble in or miscible with sulfolane. Mainly used as extractant for aromatics extraction, polymer spinning or casting solvent, natural gas and syngas, purification of refinery gas, purification and desulfurization of syngas, and dissolution of rubber and plastic. In addition, it can also be used as a printing and dyeing auxiliaries in the textile printing and dyeing industry to make the colors bright and bright.
It is used for desulfurization of natural gas, aromatic hydrocarbon extraction of reforming oil, removal of impurities such as carbon dioxide, hydrogen sulfide and organic sulfur in hydrogen.
