Claims (19)

A method of partially oxidizing a hydrocarbon with an oxide containing an oxidized hydrocarbon product using an oxygen molecule as an oxidant, comprising: a) preparing an oxygen aqueous solution in a separate vessel; b) contacting the aqueous oxygen solution with the liquid hydrocarbon to be oxidized such that the actual amount of oxygen is transferred from the aqueous phase to the hydrocarbon phase; And c) oxidizing the oxygen-containing hydrocarbon at an elevated temperature. The method of claim 1, wherein the aqueous liquid solution is prepared by dissolving oxygen in water at a pressure of about 5 bar to 200 bar. The method of claim 1 wherein the movement of oxygen occurs in the tube under conditions of backflow. 3. The method of claim 2 wherein the movement of oxygen occurs in the tube under conditions of backflow. The method of claim 1 wherein the oxygen free water formed during step (b) is recycled in step (a). The method of claim 2 wherein the oxygen free water formed during step (b) is recycled in step (a). 4. The method of claim 3 wherein the oxygen free water formed during step (b) is recycled in step (a). 5. The method of claim 4, wherein the oxygen free water formed during step (b) is recycled in step (a). The method of claim 1 wherein step (b) occurs at ambient temperature. 5. The method of claim 4 wherein step (b) occurs at ambient temperature. The method of claim 1 wherein step (b) occurs at a higher temperature than step (a). A method of partially oxidizing a hydrocarbon with an oxide containing an oxidized hydrocarbon product, using oxygen molecules as an oxidant, the method comprising: a) preparing an aqueous oxygen solution in a separate vessel; b) contacting the aqueous oxygen solution with the liquid hydrocarbon to be oxidized to transfer the actual amount of oxygen from the aqueous phase to the hydrocarbon phase; And c) oxidizing the oxygen containing hydrocarbon at elevated temperature; And d) partitioning oxygen between the mentioned product and water to remove all unreacted oxygen from the product of step (c) in a countercurrent manner. 13. The method of claim 12, wherein the water mentioned in step (d) is fresh water. 13. The process according to claim 12, wherein the water mentioned in step (d) is process water deoxygenated. 13. The process of claim 12 wherein the oxygen-enriched water produced in step (d) is recycled in step (a). The process of claim 13, wherein the oxygen-enriched water produced in step (d) is recycled in step (a). The method of claim 14, wherein the oxygen-enriched water produced in step (d) is recycled in step (a). 13. The process of claim 12 wherein the peroxide and hydroperoxides contained in the product of step (c) are decomposed before removing the unreacted oxygen of step (d). 13. The peroxide and hydroperoxides contained in the product of step (c) are decomposed and the resulting mixture is separated into hydrocarbon and hydrocarbon oxide parts having only the hydrocarbon part treated according to step (d).
