| titleOfInvention | Isomerization of bisphenols |
| abstract | A catalyst useful for the condensation of an aldehyde or ketone starting material with a phenol was an insoluble mercaptosulfonic acid compound. The heterogeneous catalysts comprise catalytically-active species represented by formula (II). L was an optional linking group and - was a bond, which catalytically-active species was attached by the bond - to an insoluble organic or inorganic support; or a catalytically-active species represented by formula (III), wherein L' was an optional linking group, - was a bond and .theta.' and .theta." were residues of .theta., and a and b were independently selected from integers equal to or greater than 1. These catalysts isomerize o,p-bisphenols to p,p-bisphenols. |
