Comparison of the kinetics of bisphenol A synthesis on promoted and unpromoted ion exchanger catalysts

Abstract

Previously evaluated kinetics of the synthesis of bisphenol A on ion exchanger catalyst modified by partial neutralization of its acidic groups by 2-mercaptoethylamine was compared with kinetics of this reaction on unmodified ion exchanger. Beside the differences in observed reaction rates, there was found only a small influence of the promoter on the form of the kinetics. The effect of 2-mercaptoethylamine as a heterogenized promoter, corrected for the influence of the diminishing of the concentration of acidic groups due to their neutralization by the promoter, was found to be comparable with the effect of ethylmercaptane as a homogeneous promoter.
