Oxidation of propene to acetone in water solutions in the presence of homogeneous catalysts
(Pd2+ + HPA-x, where HPA-x = H3+xPVxMo12-xO40, x = 1-4) is studied. This reaction is shown to be of the 1st order with respect to C3H6 and of the 0.5th order with respect to Pd. The reaction rate does not depend on the concentration of HPA-x and acidity of the catalyst solution. The apparent activation energy of the reaction is 21 kJ/mol. A reaction mechanism is proposed.
