A METHOD OF PRODUCING OXYGENATED HYDROCARBONS WHICH COMPRISES THE STEPS OF PASSING AN ELEMENTAL-OXYGEN-CONTAINING GAS UPWARDLY THROUGH A LIQUID HYDROCARBON WHICH CAN BE OXIDIZED TO WATER-SOLUBLE OXGENATED PRODUCTS, MAINTAINING SAID LIQUID HYDROCARBON UNDER PRESSURE AND AT A TEMPERATURE ABOVE ABOUT 140* C. WHILE SAID GAS PASSES THERETHROUGH TO OXIDIZE SAID LIQUID HYDROCARBON TO PRIMARY OXIDATION PRODUCTS, PASSING WATER DROPLETS DOWNWARDLY THROUGH THE MAJOR PORTION OF SAID LIQUID HYDROCARBON TO EXTRACTS THE WATER-SOLUBLE OXIDATION PROD-
