Development of efficient processes under flow conditions based on catalysts immobilized onto monolithic supported ionic liquid-like phases

Abstract

The introduction of imidazolium subunits into polystyrene-divinylbenzene (PS-DVB) polymers enables the preparation of a variety of catalytic systems. Those include the stabilization of catalytically active Pd nanoparticles (PdNPs), immobilized enzymes, and basic catalysts. The use of monolithic supports having the appropriate morphological properties is greatly advantageous for the development of efficient catalytic processes under flow conditions based on those systems. On the other hand, the combination of those supported catalytic systems and flow conditions can be further implemented, in terms of green chemistry, by the substitution of the use of traditional solvents by environmentally friendly conditions such as the use of supercritical fluids (SCFs). © 2009 IUPAC.
