AI Technical Summary

Technical Problem

Traditional catalysts in the synthesis of bisphenol compounds suffer from severe equipment corrosion, difficulty in recycling, serious environmental pollution, and long reaction times. Existing ionic liquid catalysts require inert gas protection and the use of mercapto compounds as co-catalysts.

Method used

We designed and synthesized bifunctional ionic liquids, introducing sulfonic acid and mercapto groups, for use in the catalytic synthesis of bisphenol compounds, replacing traditional catalysts, achieving efficient catalysis in a short time and enabling recycling.

Benefits of technology

Shorten reaction time, improve product selectivity, reduce equipment corrosion and environmental pollution, simplify catalyst recovery process, and reduce production costs.
