A PROCESS FOR MANUFACTURING SUBERIC ACID COMPRISING THE STEP OF CONTACTING A NITRIC ACID AQUEOUS SOLUTION AND CYCLOOCTENE IN THE PRESENCE OF A CATALYTIC COMPOSITION CONSISTING ESSENTIALLY OF A MIXTURE OF A CATALYTIC QUANTITY OF A VANADIUM COMPOUND SELECTED FROM THE GROUP CONSISTING OF VANADIUM OXIDE, AMMONIUM METAVANADATE AND ALKALI METAL METAVANADATE, AND A CATALYTIC QUANTITY OF A MANGANESE COMPOUND SELECTED FROM THE GROUP CONSISTING OF MANGANOUS OXIDE, MANGANOUS NITRATE, MANAGANOUS CHLORIDE AND MANGANOUS ACETATE, WHEREIN THE TEMPERATURE OF SAID NITRIC ACID AQUEOUS SOLUTION AND CYCLOOCTENE IS FROM 50*C.-150*C., THE ACID CONCENTRATION OF SAID NITRIC ACID AQUEOUS SOLUTION IS FROM 20-80% BY WEIGHT, AND THE RATIO OF SAID MANGANESE COMPOUND TO SAID VANADIUM COMPOUND IS 0.01 TO 100% BY WEIGHT.
