Abstract

The kinetics of catalytic ethylene oxide hydration in dilute solution and in the presence of Wofatit KPS cation exchange resin has been studied. On the basis of kinetic studies it was found that the mechanism of catalytic action does not differ from homogeneous acid catalysis. Taking into consideration the kinetic isotope effect, an A-2 type mechanism of hydration in the presence of Wofatit KPS catalyst containing 8% divinylbenzene (DVB) was suggested.

Abstract

Исследована кинетика каталитической гидратации окиси этилена в разбавленном растворе и в присутствии катионообменной смолы Wofatit KPS. На основании кинетических исследований установлено, что механизм каталитического действия не отличается от гомогенно-кислотного катализа. Имея ввиду кинетический изотопный зффект, предложен механизм гидратации типа A-2 в присутствии катализатора Wofatit KPS, содержащего 8% дивинилбензола (ДВБ).
