THE PROCESS FOR THE OXIDATION OF A C4 TO C8, SATURATED HYDROCARBON TO PROUDUCE A BORATE ESTER CONTAINING OXIDATION REACTION MIXTURE WHEREIN A MOLECULAR OXYGEN CONTAINING GAS IS CONTACTED IN A REACTION ZONE WITH A MIXTURE OF SAID HYDROCARBON IN THE LIQUID PHASE AND A LOWER HYDRATE OF BORIC ACID, COMPRISING HE COMBINATION OF EFFECTING SAID CONTACT AT A REACTION TEMPERATURE IN THE REACTION ZONE IN THE RANGE OF 140* TO 180*C., REMOVING A GASEOUS MIXTURE COMPRISING VAPORS OF SAID HYDROCARBONS AND WATER FROM SAID LIQUID PHASE DURING THE OXIDATION, AND MAINTAINING THE PARTIAL PRESSURE OF WATER IN P.S.I. IN SAID GASEOUS MIXTURE NOT GREATER THAN P WHERE P IS GIVEN BYTHE EQUATION:
