Oxygenated compounds including alcohols and ketones are produced in the continuous molecular oxygen oxidation of at least one saturated hydrocarbon supplied as a feed containing more than 95 molar per cent saturated hydrocarbons, wherein the hydrocarbon and molecular oxygen are reacted in the liquid phase in a plurality of separate oxidation satages, connected in series, in the presence of a boron adjuvant, wherein the amount of boron adjuvant present in the effluent from the first oxidation stage is sufficient to provide at least one gm. atom boron/three gm. moles of total hydrocarbon alcohol (defined as consisting of the mixture of hydrocarbon alcohol as such or in the form of the hydroperoxide and the borate esters of the hydrocarbon alcohol) in said effluent but less than an amount sufficient to result in the formation of a separate solids phase in said effluent and wherein additional boron adjuvant is added to at least one other of the oxidation stages, the. total amount of boron adjuvant employed in the oxidation being sufficient to provide at least one gram atom of boron per three gram moles of total hydrocarbon alcohol in the effluent from the last of the oxidation stages. The product alcohols are liberated by the hydrolysis of the reaction mixture. Examples use cyclohexane, cyclododecane and a C 12-14 paraffinic petroleum naphtha.
