Abstract

In a process for the continuous oxidn. of hydrocarbons to alcohols and ketones, opt in the presence of catalysts, in which the unreacted hydrocarbon is recycled to the oxid. zone, the recycled organic and/or H2O-contg. phases contg. the unreacted hydrocarbon are treated with a hydrogenation catalyst before re-entry into the oxidn. zone. The process is esp. useful for oxidising cyclohexane or cyclododecane. The treatment with the hydrogenation catalyst increases the product yield.
