The liquid-phase oxidation of tetralin in chlorobenzene at 45/sup 0/-85/sup 0/C over alumina-supported nickel oxide proceeded at a maximum rate on a 20% NiO catalyst that was calcined at 450/sup 0/C for 12 hr. The tetralin oxidation on this catalyst was 0.5 order in catalyst-tetralin ratio and first order in tetralin concentration and had an apparent activation energy of 11.8 kcal/mole. With increasing catalyst-tetralin ratio, the tetralin hydroperoxide concentration in the products decreased and the tetralyl alcohol and tetralone concentrations increased. The results were consistent with a reaction mechanism similar to the one proposed for cumene oxidation which implied that the catalytic activity of supported NiO is mainly due to its ability to decompose the hydroperoxide in the chain initiating radicals.
