Method of producing modified ion exchange resins and bisphenols |
| abstract |
In the method for producing bisphenols by reacting phenols and ketones, a modified ion exchange resin catalyst having a higher selectivity for bisphenols than a conventional modified ion exchange resin and a method for producing the same are provided.n n n A modified ion exchange resin, wherein at least one compound selected from the following (A) and (B) is ionically bonded to an acidic functional group of the acidic ion exchange resin.n n n (A) Compound represented by Formula 1 (B) Compound represented by Formula 2n n n n n n n n n Modified ion exchange resins and bisphenols |
