THE METHOD OF PRODUCING OXYGENATED DERIVATIVES OF ALIPHATIC HYDROCARBONS IN WHICH THE OXYGEN IS BONDED TO A CARON ATOM OF THE HYDROCARBON BY EFFECTING A LIMITED OXIDATION OF SUCH SATURATED ALIPHATIC HYDROCARBON GASES IN WHICH SUCH GASES ARE DIRECTLY CONTACTED WITH AN OXYGENATED SULFUR ACID OF THE CLASS CONSISTING OF SULFURIC ACID AND SULFUR TRIOXIDE AS THE OXYGEN SUPPLYING AGENT AT A TEMPERATURE IN EXCESS OF 200*C. AND NOT OVER 600*C. IN THE ABSENCE OF OTHER OXYGEN BEARING MATERIALS IN SUBSTANTIAL QUANTITIES.
