Abstract:
A method of producing hydrogen peroxide according to a continuous anthraquinone process, comprising:hydrogenating a working solution which comprises:(i) at least one reaction carrier selected from the group consisting of 2-(4-methyl-3-pentenyl) anthraquinone, di-and tetra-hydroanthroquinone derivatives thereof, 2-(4-methylpentyl) anthraquinone, and di-and tetra-hydroanthroquinone derivatives thereof, and(ii) at least one reaction carrier selected from the group consisting of 2-alkylanthraquinones and tetrahydroanthraquinone derivatives thereof, wherein the alkyl substituent of the 2-alkylanthraquinone is an alkyl substituent having from 1 to 5 carbon atoms;oxidating the hydrogenated working solution to produce hydrogen peroxide; andisolating the hydrogen peroxide,wherein the at least one reaction carrier according to (i) is present in an amount from 5 to 95 molar % relative to a total amount of reaction carriers.
