Abstract
Hydrogen peroxide is produced by a process which uses solid, insoluble, supported anthraquinone as catalyst. The supported anthraquinone is converted to supported anthrahydroquinone utilizing soluble reducing agentsor by hydrogenation with a hydrogen-donating organic substrate such as an alcohol, followed by reaction with oxygen, to regenerate anthraquinone and to form hydrogen peroxide, which can be solvent extracted from the solid catalyst.
