The invention provides application of a compound-alkyl phenylamine, shown in a formula I, as an anthraquinone regeneration catalyst in the process of producing hydrogen peroxide by adopting an anthraquinone method. In the formula I, R represents alkyl, alkoxy or alkylamino. The compound is applied in the regeneration of an anthraquinone degradation product in the process of producing the hydrogen peroxide by adopting the anthraquinone method. The inventor discovers that the compound is excellent in catalytic performance in reaction, is good in stability and overcomes the shortcoming of poor stability of active organic alkali in an anthraquinone working solution by researches. The mechanism of the excellent performance of the compound is not very definite at present and is possibly related with that the compound can keep the relatively high stability in main components-heavy aromatics of the working solution.
