The invention relates to a method for preparing dicarboxylic acid, in particular to a method for preparing adipic acid by biomimetic catalyzing oxygen oxidation of cyclohexane. The present invention selects metallophthalocyanines, mononuclear metalloporphyrins or μ-oxygen-binuclear metalloporphyrins similar in structure to biological enzymes as catalysts, and the dosage thereof is 0.1 to 1‰ of the weight of cyclohexane. As a solvent, 0.5-3.5 MPa of oxygen is passed through, the reaction temperature is controlled to be 110-160° C., and the reaction time is 4-32 hours. In the invention, the amount of catalyst is small, the reaction temperature and pressure are low, and the oxidation depth is easy to control. The catalysts used have good catalytic properties for the reaction of oxygen oxidation of cyclohexane to prepare adipic acid. The catalyst can be recycled to reduce the preparation cost. The invention adopts a one-step method to prepare adipic acid, and the reaction operation is simple and easy.
