一般描述

Sulfolane is an aprotic polar solvent, used in the separation of aromatic hydrocarbons from aliphatic hydrocarbons.
Sulfolane is widely used in combination with diisopropanolamine in the sulfinol process of removal of toxic levels of hydrogen sulfide and carbonyl sulfide from raw natural gas condensate. It is also used as an industrial solvent for photographic chemicals, polymer, and petrochemical industries.

应用

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Sulfolane may be used as an analytical reference standard for the quantification of the analyte in groundwater samples using gas chromatography-mass spectrometry technique.

Sulfolane and alkanolamines are used extensively in the processing of sour natural gases. Over many years of operation, there have been inadvertent leaks of these chemicals to groundwater and wetlands surrounding gas processing facilities, leading to uptake by vegetation. Because

Sulfolane (tetrahydrothiophene-1,1-dioxide) is used in the Sulfinol process for natural gas sweetening. At many sour-gas processing plants spills, landfills and leakage from unlined surface storage ponds have contaminated groundwaters with sulfolane. Due to its high water solubility and mobility in

Boric acid inhibited the acid-catalyzed depolymerization of cellulose in sulfolane, a non-aqueous medium, at high temperature. Formation of the dehydration products such as levoglucosenone, furfural, and 5-hydroxymethyl furfural were also effectively inhibited. Similar inhibition was observed for cellooligosaccharides and starch
