설명
Sulfolane is used in the chemical industry as a solvent for extractive distillation and chemical reactions. It is used to separate aromatic hydrocarbons (benzene, toluene and xylenes), to separate n-propyl alcohol and sec-butyl alcohol. It is also used to purify natural gas streams and for fractionation of fatty acids into saturated and unsaturated components and as a reaction solvent for the preparation of aromatic sulfonic acids, pyridines, isocyanates and pharmaceuticals. It can also be involved in the halogen exchange process and polymerization process. It is used as a plasticizer and curing agent.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
