Paragraph 0050; 0051, (2017/05/26)
The invention provides a 2 - alkyl anthraquinone synthetic method, the 2 - alkyl anthraquinone synthetic method comprises the following steps: the 2 - (4' - alkyl benzoyl) benzoic acid in the presence of a solvent through the acyl acyl; under the action of the promoter, using anhydrous aluminum ring to carry out the dehydrochlorination; reactant through hydrolysis, liquid separation, pressure reducing desolventizing, drying, to obtain 2 - alkyl anthraquinone. The beneficial effect of the present invention is: not the use of fuming sulfuric acid, mild reaction conditions, acid-free, simple process operation, the product quality is stable, and the yield of the product than the existing production process to improve the 5 - 10%.
