Abstract
The present invention relates to a novel method for conducting phase transfer catalysis in a multiphase reaction system wherein the different phases are separated by a membrane permeable to the phase transfer catalyst and its various reaction complexes. The invention also relates to membranes and a membrane-containing apparatus useful in carrying out phase transfer catalysis.
Claims40
A process for conducting heterogeneous reactions in a liquid-liquid two phase reaction system containing an organic phase and an aqueous phase, said reaction being carried out in the presence of reactants and a phase transfer catalyst, the improvement comprising:
- (a) separating said organic phase and aqueous phase with a membrane, which membrane is substantially wet by one of the phases and wherein one of the phases contains a phase transfer catalyst
- whereby said aqueous phase and organic phase remain substantially separated by said membrane during and after completion of said reaction.
