(2) The above-obtained 2-(4-ethylbenzoyl)benzoic acid and concentrated sulfuric acid are successively passed through a tube composed of a T-type mixer, a reactor A, a Y-type mixer, a reactor B, and a separator. In the reactor, the reaction produces 2-ethylanthraquinone; Yield 95.5%;Wherein, 2-(4-ethylbenzoyl) benzoic acid into the T-type mixer when the temperature is 180 ° C, concentrated sulfuric acid into the T-type mixer when the temperature is 50 ° C;The amount of 2-(4-ethylbenzoyl)benzoic acid and concentrated sulfuric acid is 1g:3mL;T-mixer temperature of 50 ° C mixing, residence time 35s;Reaction temperature in the reactor A is 120 ° C, the reaction time is 30min;Y-mixer temperature is 40 °C;Reaction temperature in reactor B is 50 °C;
