AN IMPROVED METHOD FOR TREATMENT OF AN OXIDIZED HYDROCARBON MIXTURE, AS DEFINED HEREINAFTER, TO PROMOTE COMBINATION BETWEEN A SUBSTANTIAL PORTION OF THE SAPONIFIABLE GROUPS ACCOUNTING FOR THE DIFFERENCE BETWEEN THE ACID AND. SAPONIFICATION VALUE WITH AN ORGANIC COMPOUND CONTAINING A HYDROXYL GROUP POSSESSING ALCOHOLIC CHARACTERISTICS, SAID OXIDIZED HYDROCARBON MIXTURE BEING CHARACTERIZED BY HAVING A SAPONIFICATION VALUE OF OVER 400, A SUBSTANTIAL DIFFERENCE BETWEEN ACID AND SAPONIFICATION VALUE, AND PREPARED BY LIQUID PHASE OXIDATION OF HYDROCARBONS WITH OXYGEN OF A FREE OXYGEN CONTAINING GAS, WHICH COMPRISES REACTING AN OXIDIZED HYDROCARBON MIXTURE OF THE AFORESAID CHARACTERISTICS WITH AN ORGANIC COMPOUND CONTAINING A HYDROXYL GROUP POSSESSING ALCOHOL CHARACTERISTICS FOR A PERIOD OF TIME SUFFICIENT TO COMBINE WITH SAPONIFIABLE GROUPS OF SAID MIXTURE AN AMOUNT OF SAID ALCOHOLIC COMPOUND IN EXCESS OF THE THEORETICAL EQUIVALENT BASED ON THE ACID VALUE OF SAID MIXTURE, SAID REACTION BEING CARRIED OUT IN THE PRESENCE OF AN ESTERIFICATION CATALYST CAPABLE OF CAUSING SAID REACTION TO CONTINUE BEYOND THE EXTENT OF COMBING SAID ALCOHOLIC COMPOUND IN AN AMOUNT THEORETICALLY EQUIVALENT TO THE ACID VALUE OF SAID MIXTURE WHEREBY A SUBSTANTIAL POR TION OF THE SAPONIFIABLE GROUPS ACCOUNTING FOR THE DIFFERENCE BETWEEN THE ACID AND SAPONIFICATION VALUES OF SAID MIXTURE ARE COMBINED WITH SAID ALCOHOLIC COMPOUND.
