Abstract:
An improved process for oxidizing a cycloalkane in a reaction mixture to form a product mixture containing a corresponding alcohol and ketone, the improvement comprising:contacting the reaction mixture with a source of oxygen and a catalytic amount of a heterogenous catalyst selected from the group consisting of (1) gold, (2) a sol-gel compound of gold, and (3) a sol-gel compound comprised of (a) one or more members selected from a first group consisting of Cr, Co and Ti and (b) one or more members selected from a second group consisting of Zr, Ta, Nb, Si, Mg, Al and Ti with the proviso that hydrogen is not present in the reaction mixture if the catalyst is gold supported on titania or sol-gel compound of gold supported on titania, that the selected members of (b) are combined with an oxide, and that members of group (a) cannot be the same as the members of group (b).
