A catalytic solution system for manufacturing terephthalic acid is disclosed and its method. The system uses a Co-Mn-Br acetate solution (CMB) that is applied in an oxidation reaction, when the weight ratio of each component is (Co %x2.7)+(Mn %x2.9 %)>Br %. CoBr2 and MnBr2 are introduced as a source of Br for the CMB solution. Compensation for any shortage of Co and Mn, after such a supplement, can be made from cobalt acetate and manganese acetate without using highly corrosive HBr. The present invention provides a method of preparing a catalyst for manufacturing terephthalic, wherein, in the stirring action of para-xylene with a gas containing oxygen, the above catalytic solution system is used.
