Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
113 words
IN A PROCESS OF OXIDIZING METHYL CYCLOHEXANE WHERE IN A SOLUTION OF METHYL CYCLOHEXANE IN ACETIC ACID IS INTRODUCED INTO A REACTION ZONE, MOLECULAR OXYGEN IS PASSED THROUGH SAID SOLUTION WHILE MAINTAINING A TEMPERATURE BETWEEN 50* AND 250*C., PASSING GASEOUS EFFLUENT FROM SAID REACTION ZONE THROUGH A CONDENSER SYSTEM TO REMOVE UNREACTED CONSTITUENTS FOR RECYCLE TO SAID REACTIO ZONE, COOLING SAID REACTION ZONE, AND DISTILLING THE CONTENTS OF SAID REACTION ZONE TO YIELD A PRODUCT COMPRISING FORMIC AND ACETIC ACIDS IN EXCESS OF THE AMOUNT OF ACETIC ACID ORIGINALLY INTRODUCED INTO SAID REACTION ZONE, THE IMPROVEMENT OF OXIDIZING THE METHYL CYCLOHEXANE IN THE PRESENCE OF 0.1 TO 10% BY WEIGHT OF MANGANESE BROMIDE.
Claim 2
Dependent Claim
