description The invention provides a method for preparing long-carbon-chain dibasic acid through a co-oxidation reaction, a component A, a component B, a nitric acid aqueous solution and a catalyst are mixed and heated until complete reaction to obtain a reaction solution containing required long-carbon-chain dibasic acid, the component A comprises cyclic alcohol with 8-16 carbon atoms, cyclic ketone with 8-16 carbon atoms, 1, 1, 1, 1, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3- the component A comprises one or more of 1, 2-dihydroxy cycloalkane and a compound shown in a formula I, and the component B comprises one or more of cyclic alcohol with 4-6 carbon atoms, cyclic ketone with 4-6 carbon atoms and 1, 2-dihydroxy cycloalkane with 4-6 carbon atoms. The method has the beneficial effects that the addition of the low-carbon cyclic alcohol or ketone can play a role in inhibiting series decarboxylation side reaction, reducing the dosage of nitric acid, r
