The invention discloses a method for preparing an anthraquinone derivative from anthracene and producing hydrogen peroxide. The method comprises the following steps: (1) preparing a reaction product containing an alkyl anthracene system from anthracene; (2) oxidizing the alkyl anthracene system prepared in the step (1) to prepare an alkyl anthraquinone system; (3) mixing the alkyl anthraquinone system prepared in the step (2), a non-polar solvent and a polar solvent to prepare an alkyl anthraquinone working solution; and (4) carrying out hydrogenation, oxidation and extraction on the alkylanthraquinone working solution prepared in the step (3) to produce hydrogen peroxide. The invention innovatively provides a technical route that the mixed alkyl anthracene prepared from anthracene through alkylation does not need to be separated, can be directly oxidized to prepare the mixed alkyl anthraquinone and is used for producing hydrogen peroxide, so that the technological process is greatly simplified, and the techn
