Abstract:
Catalysts having a higher total capacity and containing fewer organic impurities are provided for condensation, addition and esterification reactions, as well as a process for preparing these catalysts and for use of the catalysts for preparation of bisphenols.

Claim (Index 1):
A process for preparing a catalyst gel, the process comprising:\n mixing crosslinked bead polymer comprising monomers derived from:\n at least one monoethylenically unsaturated aromatic compound selected from the group consisting of styrene, \u03b1-methylstyrene, vinyltoluene, ethylstyrene, t-butylstyrene, chlorostyrene, bromostyrene, chloromethylstyrene vinylnaphthalene, and mixtures of thereof, and \n at least one multiethylenically unsaturated compound selected from the group consisting of divinylbenzene, divinyltoluene, trivinylbenzene, octadiene, triallyl cyanurate, and mixtures thereof, and \n sulphuric acid having an initial concentration of 98% by weight to 99% by weight to form a reaction mixture in the presence of less than 1 wt. % swelling agent, based on the weight of the mixture; sulphonating the crosslinked bead polymer at a temperature of 50\u00b0 C. to 160\u00b0 C. to produce sulphonated cross-linked bead polymers, wherein the concentration of the sulphuric acid in the reaction mixture is at least 75% by weight, and the reaction mixture comprises 70% to 95% by weight sulphuric acid and 5% to 30% by weight bead polymer, based on the total amount of sulphuric acid and bead polymer, and a sum total of the percentages by weight of sulphuric acid and bead polymer in the reaction mixture is >98% by weight; and reacting the sulphonated crosslinked bead polymers with 2,2\u2032-dimethylthiazolidine to produce a catalyst gel.
