Because of its high thermal stability and stability to acids and bases, it is an excellent solvent. It can be used to extract aromatic hydrocarbons from aliphatic hydrocarbons and to remove acidic gases from gas mixtures. Sulfolane can be used as a solvent for polymer compounds such as copolymer, polyvinyl fluoride, etc., for spinning, manufacturing film, etc. It can also be used as a plasticizer for cellulose ether, polyvinyl alcohol, polyethylene, polyvinyl chloride, polyamide, etc., and an additive for acrylic fiber spinning. Others can also be used for the separation of fatty acids, extraction of non-cellulose components from wood and so on. Sulfolane can be used as condenser carrier because of its high boiling point, good thermal stability and non-corrosion. Added to the press oil can improve corrosion resistance, fire resistance, thermal stability, viscosity and other properties.
