Sulfolane is a highly polar, water-miscible solvent widely used in the petrochemical and refining industries. It is especially effective in aromatic extraction processes, helping separate valuable hydrocarbons with high efficiency and stability. Known for its excellent thermal and chemical resistance, Sulfolane ensures consistent performance under demanding industrial conditions. Sarchem Labs supplies high-purity Sulfolane suitable for laboratory research and large-scale industrial applications.
Synonym: sulfolane, tetramethylene sulfone, tetrahydrothiophene 1,1-dioxide, sulfolan, sulpholane, sulfalone, sulphoxaline, 1,1-dioxothiolan, dioxothiolan, thiophan sulfone
