SULFOLANE Chemical compatibility with O-rings, rubbers, & plastics

Sulfolane is a colorless, high-boiling, polar solvent with the chemical formula C4H8O2S. It is used in various industrial and chemical applications, primarily as a solvent for the extraction of aromatics from hydrocarbon streams in the petrochemical industry. Sulfolane is also employed in the production of certain polymers and resins, where it acts as a solvent and processing aid. Its high polarity and stability make sulfolane an effective solvent for a wide range of organic compounds. Proper handling and storage of sulfolane are essential to maintain its quality and prevent contamination. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial to prevent skin and eye irritation and other health hazards. Its versatility and effectiveness as a solvent make sulfolane a valuable chemical in numerous industrial applications, although its use requires careful control to prevent environmental and health impacts.
