Abstract:
A process for conditioning monodisperse ion-exchangers for the catalysis of condensation reactions, addition reactions, transesterifications, esterifications or alkylation reactions, comprising the steps ofa) moistening monodisperse ion-exchangers with water, b) suspending the moistened ion-exchangers in oxygen-free completely de-ionized water, c) washing the suspended ion-exchanger with oxygen-free completely deionized water until constant conductivity is attained, d) after washing, discharging the completely de-ionized water, e) admixing an oxygen-free OH component to the monodisperse ion-exchanger, f) dehydrating the mixture in a continuously operated circulating apparatus with a distillation unit, and g) transferring the suspension comprising the monodisperse ion-exchanger and OH component into a reaction vessel.
