Method of producing dicarboxylic acids

Claim 1

THE METHOD OF PRODUCING AN ALKANEDIOIC ACID HAVING EIGHT TO TWELVE CARBON ATOMS FROM A MONOOLEFINIC CYCLOALKENE HYDROCARBON, COMPRISING: SUBJECTING THE CYCLOALKENE WHICH HAS THE SAME NUMBER OF CARBON ATOMS AS SAID ALKANEDIOIC ACID TO OZONIATION AT A TEMPERATURE BELOW ABOUT 25*C, BY SUPPLYING A GAS CONTAINING ABOUT 2% TO 7% OZONE BY WEIGHT TO THE CYCLOALKENE HYDROCARBON, SAID CYCLOALKENE BEING PRESENT, IN AN AMOUNT AT LEAST ABOUT 10% OF THE TOTAL WEIGHT, DISSOLVED IN A LIQUID SATURATED LOWER FATTY ACID MEDIUM, THEREAFTER HEATING SAID MEDIUM CONTAINING THE PRODUCT OF OZONIZATION TO A TEMPERATURE OF APPROXIMATELY 65*-70* C, WHILE PASSING GAS RICH IN FREE OXYGEN INTO INTIMATE CONTACT THEREWITH, TO INTITATE OXIDATION OF SAID PRODUCT WITH PRODUCTION OF SAID ALKANEDIOIC ACID, FURTHER RAISING THE TEMPERATURE, WHILE CONTINUING TO SUPPLY SAID OXYGEN-RICH GAS TO SAID MEDIUM, IN ACCORDANC EWITH A PREDETERMINED SCHEDULE OF AT LEAST TWO FURTHER TEMPERATURE INCREASES EACH OF APPROXIMATELY 5*20*C. TO A FINAL TEMPERATURE OF APPROXIMATELY 100*110*C, THE TEMPERATURE BEING HELD RELATIVELY CONSTANT BEFORE AND AFTER EACH OF SAID FURTHER TEMPERATURE INCREASES FOR TIME PERIODS HAVING SUBSTANTIAL INDIVIDUAL DURATIONS, ALL OF SAID DURATIONS BEING OF THE SAME ORDER OF MAGNITUDE, AND RECOVERING SAID ALKANEDIOIC ACID FROM SAID MEDIUM AFTER THE LAST OF SAID TIME PERIODS.

Claim 2

THE METHOD OF PRODUCING AN ALKANEDIOIC ACID HAVING EIGHT TO TWELVE CARBON ATOMS FROM A MONOOLEFINIC CYCLOALKENE HYDROCARBON, COMPRISING: SUBJECTING THE CYCLOALKENE WHICH HAS THE SAME NUMBER OF CARBON ATOMS AS SAID ALKANEDIOIC ACID TO OZONIATION AT A TEMPERATURE BELOW ABOUT 25*C, BY SUPPLYING A GAS CONTAINING ABOUT 2% TO 7% OZONE BY WEIGHT TO THE CYCLOALKENE HYDROCARBON, SAID CYCLOALKENE BEING PRESENT, IN AN AMOUNT AT LEAST ABOUT 10% OF THE TOTAL WEIGHT, DISSOLVED IN A LIQUID SATURATED LOWER FATTY ACID MEDIUM, THEREAFTER HEATING SAID MEDIUM CONTAINING THE PRODUCT OF OZONIZATION TO A TEMPERATURE OF APPROXIMATELY 65*-70* C, WHILE PASSING GAS RICH IN FREE OXYGEN INTO INTIMATE CONTACT THEREWITH, TO INTITATE OXIDATION OF SAID PRODUCT WITH PRODUCTION OF SAID ALKANEDIOIC ACID, FURTHER RAISING THE TEMPERATURE, WHILE CONTINUING TO SUPPLY SAID OXYGEN-RICH GAS TO SAID MEDIUM, IN ACCORDANC EWITH A PREDETERMINED SCHEDULE OF AT LEAST TWO FURTHER TEMPERATURE INCREASES EACH OF APPROXIMATELY 5*20*C. TO A FINAL TEMPERATURE OF APPROXIMATELY 100*110*C, THE TEMPERATURE BEING HELD RELATIVELY CONSTANT BEFORE AND AFTER EACH OF SAID FURTHER TEMPERATURE INCREASES FOR TIME PERIODS HAVING SUBSTANTIAL INDIVIDUAL DURATIONS, ALL OF SAID DURATIONS BEING OF THE SAME ORDER OF MAGNITUDE, AND RECOVERING SAID ALKANEDIOIC ACID FROM SAID MEDIUM AFTER THE LAST OF SAID TIME PERIODS.
