The authors examined the influence on oxidation of isopropylbenzene (IPB) not only of naphthenates of metals from Group II of the periodic system, but also of compounds which, in their oopinion, should form more labile complexes with cumenyl hydroperoxide (CHP) than napthenates. It is shown that a virtually complete absence of an induction period is a common feature in oxidation of isopropylbenzene in the presence of alkaline-earth naphthenates and also of various zinc and cadmium compounds activated with 1,10-phenanthroline. The magnitude of the synergistic effect in the isostructural series of mixed catalytic systems decreases in the folling series: alkaline-earth naphthelnates, alkali naphthenate, sinc (or cadmium) nathenates. It follows that systems containing zinc (or cadmium) compounds together with N-heterocycles are the most promising of the mixed catalysts studied for selective oxidation of IPB to the hydroperoxide.
