Abstract

1425202 Hydrogen peroxide E I DU PONT DE NEMOURS & CO 19 June 1973 [20 June 1972] 29061/73 Heading C1A [Also in Division C2] Hydrogen peroxide is produced in a cyclic process by reduction of alkylated anthraquinone dissolved in a solvent, followed by oxidation of the produced anthrahydroquinone in which as the anthraquinone is used a tetrahydroanthraquinone of Formulae I or II in which R 1 is a C 1 -C 6 alkyl group, R 2 or R 3 are H or C 1 -C 6 alkyl and R 4 is C 1 -C 10 alkyl, optionally also in the presence of a compound of Formula VI wherein (a) R 6 represents a hydrogen atom and R 5 represents a C 1 -C 6 alkyl group or (b) R 6 represents H or is as defined above for R 4 and R 5 represents a group where R 6 is H or is as defined above for R 4 .
