What is sulpholane?

Sulfolane is a clear, colorless, and non-reactive organic compound with the chemical formula C4H8O2S. It is a highly polar and aprotic solvent that has a high boiling point of 288 °C, making it ideal for use in high-temperature applications.

Sulfolane is commonly used as a solvent in the petrochemical industry, particularly in the refining of natural gas and the production of aromatics. It is also used as a solvent in the manufacture of polyphenylene sulfide (PPS), a high-performance thermoplastic used in the automotive and electronics industries.

Sulfolane is considered to be a relatively safe solvent, with low toxicity and low flammability. However, long-term exposure to high concentrations of sulfolane may cause irritation to the eyes, skin, and respiratory system. It is important to handle sulfolane with care and to ensure that it is used in a well-ventilated area.
