Abstract: 1,132,693. Hydrogen peroxide. LAPORTE CHEMICALS Ltd. 15 Nov., 1965 [17 Nov., 1964]. No. 46786/64. Heading C1A. H 2 0 2 is prepared by a cyclic process by the catalytic hydrogenation and oxidation of a working solution containing 2-ethylanthraquinone and 2-ethyltetrahydroanthraquinone, or 2-ethyltetrahydroanthraquinone alone, in a solvent mixture of 25-80% of at least one cycloalkanol ester with the remainder being at least one aromatic hydrocarbon, wherein the degree of hydrogenation is at least 35% of the theoretical, at least 35% of the quinones is 2-ethyltetrahydroanthraquinone, and the temperature and concentration of ester are such that the capacity of the solution to produce H 2 O 2 is 6.5 g./l. The catalyst may be Pd on an Al or aluminosilicate carrier, and may be removed from the working solution by filtration. The working solution may contain 20-120 g./l. solids, other than quinones and quinols, derived from the quinones during the recycling. The hydrogenation temperature may be 70-150‹ C. without said solids or 50-110‹ C. with solids. Specified esters or methylcyclohexanol acetate, propionate and butyrate and specified hydrocarbons are those having b.p.'s of at least 138‹ C. e.g. petroleum fraction of 145-210‹ C.

Abstract: In the production of H2O2 by cylic hydrogenation and oxidation the working solution contains at least one naphthoquinone having the general formula in which R1 and R2 may be the same or different and represent alkyl groups having up to 9 carbon atoms, and R3 to R6 may be the same or different and represent hydrogen atoms or alkyl groups having up to 9 carbon atoms. Examples of suitable naphthoquinones include 2,3-diethyl-, 2-methyl-3-ethyl-, and 2-methyl-3-n-propyl-naphthoquinones and the new compounds 2-methyl-3n-butyl- and 2,6-dimethyl-3-enthyl-naphthoquinone. Suitable solvents include mixtures of benzene or polyalkyl benzenes with ester of cyclohexanol and/or alkyl-cyclohexanols e.g. 50/50 v/v. of benzene and methyl cyclohexanol acetate (sextate) and hydrocarbon/ketone mixtures in which the ketone may be di-isobutyl ketone.
