2 - (4 -pentylbenzoyl) benzoic acid and 2 -pentyl anthraquinone and a preparation method thereof relate to the technical field of fine chemicals. The preparation method of 2 - (4 -pentylbenzoyl) benzoic acid with a high tertiary-secondary ratio comprises the following steps: reacting phthalic anhydride, a solvent, a Fourier reaction catalyst and tert-amyl benzene in a hypergravity reactor, and introducing a working gas in the reaction process. ABB acid was significantly boosted after the reaction, so that the 2 -pentyraquinone obtained had a high tertiary-to-secondary ratio. The hydrogen chloride gas generated in the reaction process can be effectively removed, the isomerization reaction quantity is reduced, and the tertiary secondary ratio of the product is improved.
