Popis:	Possibilities of decreasing the ability of strong-acid ion-exchanger catalysts to retain water were investigated in a case study of bisphenol A synthesis for to diminish effects of water as reaction product on the kinetics of the catalyzed reaction. It was found that partial thermal desulfonation or neutralization of about 30-40% acid groups with 2-aminoethanethiol can produce catalysts which exhibit, in the presence of technologically significant concentration of water, a higher activity in bisphenol A synthesis than conventional ion-exchanger catalysts.
