General description
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.
Application
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.
