| Description | In the present invention, there is disclosed a phase transfer catalyst containing ions derived from 1,1-dialkylpiperazin-1-ium, wherein the alkyl groups are selected independently on each other from the group consisting of benzyl and n-alkyl group having 1 to 18 carbon atoms, being immobilized by an ionic linkage onto a synthetic polymeric ion-exchange resin. The immobilization on the ion-exchange resin is carried out such that a solution of 1,1-dialkylpiperazinium salt in water or in a lower alcohol or in a mixture thereof is continuously washed vie a column filled with a corresponding ion exchange resin or it is continuously mixed with the ion exchange resin to obtain a required state of the ion exchange resin saturation. |
