Abstract
The present invention relates to a method for preparing hydrocarbon double acids using a cyclic hydrocarbon oxidation catalyst, wherein adipic acid and dodecanedioic acid may be produced with high yield while solving the problem of environmental pollution, the adipic acid and the dodecanedioic acid being prepared by using an oxidation reaction of a cyclohexane-cyclohexanone mixture and an oxidation reaction of a cyclododecane-cyclododecanone mixture, respectively, in the presence of a vanadium phosphate oxide-based catalyst and/or a cobalt-manganese oxide-based catalyst.
