Description
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.More related product prices
