| Abstract: | In the presence of the catalytic system (PdSO4+HPA), where HPA=H9PMo6V6O40, octene-1 is found to be selectively (95%) oxidized to octanone-2. The optimum concentration ratio for catalyst stability is HPA]:PdSO4]=30–40. The substitution of PdCl2 for PdSO4 leads to the formation of all three isomeric octanones without decrease of the overall selectivity. Effective rate constants and the apparent activation energy have been determined in the temperature range from 60 to 80 °C.
