Product Introduction:

Sulfolane, also known as tetrahydrothiophene-1,1-dioxide, chemical formula C4H8O2S, colorless transparent liquid.

Sulfolane is an excellent aprotic polar solvent, miscible with water, acetone, toluene, etc. It is also an ideal solvent for the extraction of aromatic hydrocarbons in petrochemical industries.

Sulfolane is easy to decompose at high temperature. When the temperature is below 220 °C, the decomposition speed is relatively slow, but when the temperature exceeds 220 °C, the decomposition speed increases sharply with the increase of temperature.

Excessive temperature will cause sulfolane to decompose into black polymer and sulfur dioxide. When there is air, due to the oxidation of air, the release of sulfur dioxide in the solvent system is more than when there is no air.

Sulfolane solvent has the characteristics of high solubility to 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 extraction technology in the world.

Nature and Specifications:

Product Packaging


Product Usage:

As a result of its high thermal security, Sulfolane is stable to bases as well as acids, making it an exceptional solvent.

It is a polar solvent with solid solubility and great selectivity. The majority of organic compounds as well as polymers can be dissolved in sulfolane or miscible with it.

It is used for filtration of gas, syngas, refinery gas, filtration and also desulfurization of syngas, and also as a solvent for rubber as well as plastics.

Sulfolane is additionally made use of as extractant for fragrant extraction, polymer spinning or casting solvent.

Utilized as gas chromatography fixed liquid and analytical reagent, also utilized in natural synthesis

Additionally, it can also be utilized in fabric printing and coloring market as printing and dyeing accessories, which can make the shade intense as well as bright.

It is used as a careful solvent for gas-liquid removal, drawing out fragrant hydrocarbons from aliphatic hydrocarbons, and getting rid of acid gases from gas mixtures.

Sulfolane can be taken advantage of as a solvent for polymer substances such as polyacrylonitrile, acrylonitrile copolymer, polyvinyl fluoride, and so forth, for rotating, making films, etc.

In various other facets, it can likewise be utilized for the splitting up of fats, removal of non-cellulose elements from timber, etc.

Because of its high boiling point, good thermal stability and also non-corrosiveness, sulfolane can be made use of as a condenser provider.

Including in push oil can improve residential or commercial properties such as deterioration resistance, fire resistance, thermal stability, viscosity, and so on.
