Hydrogenation of a working solution in a hydrogen peroxide production process

摘要

The invention relates to a method of hydrogenating alkyl anthraquinones and/or alkyl hydroanthraquinones to alkyl anthrahydroquinones and/or alkyl hydroanthrahydroquinones, wherein the reaction is carried out in the presence of a catalyst under electromagnetic irradiation. Additionally the invention relates to a method of hydrogenating a working solution in a hydrogen peroxide production process, said working solution containing alkyl anthraquinones and/or alkyl hydroanthraquinones dissolved in at least one solvent, to convert said quinones to corresponding alkyl anthrahydroquinones and/or alkyl hydroanthrahydroquinones, wherein the reaction is carried out in the presence of a catalyst under electromagnetic irradiation.
