Process for producing hydrogen peroxide

摘要

Process for producing hydrogen peroxide The invention relates to a process for producing hydrogen peroxide by the cyclic anthraquinone process. According to the invention, the rate of oxidation of a hydrogenated working solution containing a tetrahydroanthrahydroquinone derivative is increased if the oxidation is carried out in the presence of a secondary amine. Preferably a slightly water-soluble secondary amine having a boiling point of at least 150° C., in a quantity of 0.001 to 2 mol per mol of tetrahydro compounds, is used.
