Barreled sulfolane spot direct delivery of industrial grade tetrahydrothiophene sulfone CAS126-33-0

Sulfolane, also known as tetrahydrothiophene-1,1-dioxide, chemical formula C4H8O2S, is a colorless and transparent liquid. It is an excellent non proton polar solvent and can be miscible with water, acetone, toluene, and other solvents. It is also an ideal solvent for aromatic hydrocarbon extraction processes in petrochemical industry. Sulfolane is prone to decomposition at high temperatures. At temperatures below 220 ℃, the decomposition rate is relatively slow, but above 220 ℃, as the temperature increases, its decomposition rate sharply increases. Excessive temperatures will promote the decomposition of sulfolane into black polymers and sulfur dioxide. In the presence of air, due to the oxidation of air, the release of sulfur dioxide in the solvent system is greater than in the absence of air.

Cyclobutane is an excellent solvent due to its high thermal stability and stability to acids and bases. It can be used to extract aromatic hydrocarbons from fatty hydrocarbons and remove acidic gases from gas mixtures. Sulfolane can be used as a solvent for polymer compounds such as polyacrylonitrile, acrylonitrile copolymers, polyfluoroethylene, etc., used for spinning, film manufacturing, etc. It can also be used as a plasticizer for cellulose ether, polyvinyl alcohol, polyethylene, polyvinyl chloride, polyamide, etc., and as an additive for acrylic fiber spinning. Other applications include the separation of fatty acids and the extraction of non cellulose components from wood. Due to its high boiling point, good thermal stability, and non corrosiveness, sulfolane can be used as a condenser carrier. Adding it to press oil can improve properties such as corrosion resistance, flame resistance, thermal stability, viscosity, etc.
