Doping of selected schiff polybases with heteropolyacids: catalytic properties of the products

It has been demonstrated that conjugated polyimines can serve as convenient catalytic supports on which catalytically active species can be molecularly dispersed using the dopin(protonation) reaction analogously as in the case of polyaniline. In particular, polyimine prepared via condensation of p-p...

Description
Summary:It has been demonstrated that conjugated polyimines can serve as convenient catalytic supports on which catalytically active species can be molecularly dispersed using the dopin(protonation) reaction analogously as in the case of polyaniline. In particular, polyimine prepared via condensation of p-phenylenediamine and terephtalaldehyde can be protonated with 12-molybdophosphoric acid to give a new catalyst active in alcohol conversion. In isopropanol conversion this catalyst shows enhanced selectivity towards acetone formation as compared to unsupported crystalline heteropolyacid studied in the same experimental conditions.
