It has been demonstrated that conjugated polyimines can serve as conve
nient catalytic supports on which catalytically active species can be
molecularly dispersed using the doping(protonation) reaction analogous
ly as in the case of polyaniline. In particular, polyimine prepared vi
a condensation of p-phenylenediamine and terephtalaldehyde can be prot
onated with 12-molybdophosphoric acid to give a new catalyst active in
alcohol conversion. In isopropanol conversion this catalyst shows enh
anced selectivity towards acetone formation as compared to unsupported
crystalline heteropolyacid studied in the same experimental condition
