Claim 1
Independent Claim
103 words
THE PROCESS WHICH COMPRISES OXIDIZING LIQUID HYDROCARBON MATERIAL IN THE LIQUID PHASE BY GASEOUS OXYGEN AT TEMPERATURES IN THE RANGE 150* TO 200* C. UNDER PRESSURE MAINTAINING THE HYDROCARBON IN THE LIQUID STATE, SAID LIQUID HYDROCARBON MATERIAL HAVING AN INITIAL DISTILLATION TEMPERATURE ABOVE 0* C. AND AT LEAST 80% DISTILLING OVER AT TEMPERATURES BELOW 100* C. AND BEING PRINCIPALLY COMPOSED OF SATURATED ALIPHATIC HYDROCARBONS HAVING BOILING POINTS IN THE RANGE 27* 100* C., SAID OXIDATION BEING CARRIED OUT IN A POOL OF REACTION MIXTURE CONTAINING OXIDATION PRODUCTS OF THE HYDROCARBON MATERIAL, TO WHICH POOL AN OXYGEN-CONTAINING GAS IS SUPPLIED AND 0.7 TO 1.8
