    • A process for producing hydrogen peroxide by subjecting a working solution containing anthraquinones as the reaction medium, to reduction and oxidation alternately, which process is characterized in that (1) the anthraquinones as the reaction medium contained in the working solution are a mixture of an alkyl-substituted anthraquinone and an alkyl-substituted tetrahydroanthraquinone, (2) in the reduction step, the total amount of the alkyl-substituted tetrahydroanthraquinone in the working solution and part or the total amount of the alkyl-substituted anthraquinone in the working solution are reduced, and (3) in the working solution after the reduction step, the content of the alkyl-substituted anthrahydroquinone formed is kept higher than the content of the alkyl-substituted tetrahydroanthrahydroquinone formed.
    • 通过对含有蒽醌作为反应介质的工作溶液进行交替的还原和氧化而生产过氧化氢的方法,其特征在于:(1)工作溶液中含有的作为反应介质的蒽醌是烷基 取代的蒽醌和烷基取代的四氢蒽醌,(2)在还原步骤中,工作溶液中烷基取代的四氢蒽醌的总量和工作溶液中烷基取代的蒽醌的总量以及总量减少, 和(3)在还原步骤后的工作溶液中,形成的烷基取代的蒽醌的含量保持高于形成的烷基取代的四氢蒽氢醌的含量。
