  • Patent number: 5294739
    Abstract: The invention relates to a process for the catalytic oxidation of hydrocarbons with molecular oxygen using a cobalt-containing molecular sieve material having the cobalt ions substantially incorporated in the crystal lattice of the molecular sieve. Preferably, the oxidation is carried out with a molecular sieve containing from about 0.1% to about 10% by weight of cobalt and wherein the cobalt ions are substantially trivalent when the reaction starts. Preferably, the catalyst is a cobalt containing phosphate based molecular sieve material of the structure type 5, 31, 36, 37, 40, 50 and mixtures thereof and the hydrocarbons oxidized are from the group consisting of straight chain alkanes, alkenes, cycloalkanes and cycloalkenes which contain from about 3 to about 20 carbon atoms.
