The application discloses a synthesis method of 9-bromoanthracene and belongs to the technical field of organic synthesis. Anthracene is used as raw material, inorganic bromide salt is used as a bromine source, hydrogen peroxide is used as an oxidant, and 9-bromoanthracene is synthesized in a mixed solvent under the catalysis of a composite Lewis acid with high selectivity; the crude product is purified through step-by-step fractional recrystallization to obtain a high-purity product. Through the synergistic effect of the composite catalytic system and the mixed solvent, the generation of the difficult-to-remove by-product 9,10-dibromoanthracene is inhibited from the source, and the efficient separation of the product and the key impurities can be realized without column chromatography by combining the gradient cooling fractional crystallization process. The process is green and safe, simple to operate, low in cost and easy to industrialize, and the prepared 9-bromoanthracene can meet the application requirements in high-end fields such as OLED photoelectric materials.
