The invention concerns a process for production of hydrogen peroxide according to the anthraquinone process comprising the steps of alternate hydrogenation and oxidation of anthraquinones and tetrahydro anthraquinones in a working solution comprising a mixture of alkyl-substituted anthraquinones and alkyl-substituted tetrahydro anthraquinones dissolved in at least one organic solvent, wherein from 10 to 55 mole % of the anthraquinones and the tetrahydro anthraquinones are substituted with one amyl group, and the molar ratio of alkyl-substituted tetrahydro anthraquinones to alkyl- substituted anthraquinones is at least 1:1. The invention also concerns a composition useful as a working solution in said process.
