ABSTRACT:
Hydrogen peroxide production by oxidation of a 2-alkyl-9,10-dihydroxyanthracene, especially the 2-(t-butyl) compound, and catalytic hydrogenation of the resulting 2-alkylanthraquinone back to the dihydroxy compound, using a water-insoluble (bipyridyl) rhodium complex as hydrogenation catalyst. Especially such process carried continuously in a cell in which an organic phase is separated by a porous membrane from an aqueous phase, and the anthraquinone is hydrogenated on the organic side of the cell and hydrogen peroxide is obtained from the aqueous phase. Preferably the rhodium complex is formed with a bipyridyl ligand attached to polystyrene beads, whereby to assure that rhodium is not carried into the hydrogen peroxide production side of the cell.
