Catalyst for synthesizing bisphenol and method for making same |
摘要 |
A sulfonated organic polymer, such as a sulfonated polystyrene ion-exchange resin is provided having organic mercaptan groups attached to backbone sulfone radicals by covalent nitrogen-sulfur linkages. A method for making such sulfonated organic polymer is also provided. The ion-exchange resin can be used to effect phenol-ketone condensation in the synthesis of bisphenols.
