Claim 1
Independent Claim
149 words
A PROCESS FOR THE OXIDATION, AS A STOCK, OF A DEWAXED, WATER AND ALKALI WASHED FRACTION OF A HYDROCARBON SYNTHESIS LIQUID CONTAINING MORE THAN FIVE CARBON ATOMS PER MOLECULE AND CONTAINING BOTH OLEFIINC AND PARAFFINIC HYDROCARBONS OBTAINED FROM THE CATALYTIC REDUCTION OF CARBON MONOXIDE WITH HYDROGEN WHICH COMPRISES OXIDIZING SAID FRACTION IN AN OXIDATION ZONE AT 200 TO 500*F. WITH MOLEUCLAR OXYGEN IN THE PRESENCE OF A CATALYST SYSTEM COMPRISNG BORMINE IN A FORM SELECTED FROM THE CLASS CONSISTING OF IONIC, COMBINED AND ELEMENTAL BROMINE AND A HEAVY METAL OXIDATION CATALYST IN THE PRESENCE OF AN ACIDIC REACTION MEDIUM COMPRISING A LOWER ALIPHATIC MONOCARBOXYLIC ACID CONTAINING 2 TO 8 CARBON ATOMS WHILE MAINTAINING A LIQUID PHASE IN SAID OXIDATION ZONE WHEREBY A MONO-OLEFINIC KETO MONOCARBOXYLIC ACID CONTAINING MORE CARBON ATOMS PER MOLECULE THAN SAID FEED STOCK IS FORMED AS THE MAJOR PRODUCT, AND RECOVERING SAID MONO-OLEFINIC KETO MONOCARBOXYLIC ACID.
