Method for producing hydrogen peroxide |
摘要 |
The present invention provides a method for producing hydrogen peroxide, comprising the steps of: alternately reducing and oxidizing a working solution containing anthraquinone compounds as a reaction medium, wherein a mixture of alkyl-substituted anthraquinones and alkyl-substituted tetrahydroanthraquinones in a molar ratio of from 2:1 to 8:1 is used as the anthraquinone compounds in the working solution, in the reduction step all of the tetrahydroanthraquinones and some or all of the anthraquinones in the working solution are reduced; and keeping the content of alkyl-substituted anthrahydroquinones in the working solution after the reduction step and before the oxidation step higher than the content of alkyl-substituted tetrahydroanthrahydroquinones, wherein ethylanthraquinone and cthyltctrahydroanthraquinonc arc used as anthraquinone compounds in the working solution in a total proportion of both of from 10 to 45 mol% of all of the anthraquinone compounds in the working solution.
