Abstract
Hydrogen peroxide is produced by the successive catalytic hydrogenation and autoxidation in a solvent medium, with recycling to the hydrogenation stage after aqueous extraction of the hydrogen peroxide produced in the oxidation stage, of a mixture of two or more alkyl anthraquinones. Mixtures specified are 20% of 2-ethyl anthraquinone and 80% of 2-isopropyl anthraquinone; 27% of 2-ethyl anthraquinone and 73% of 2-sec. butyl anthraquinone; 45% of 2-ethyl anthraquinone and 55% of 2-tert. butyl anthraquinone; 65% of 2-isopropyl anthraquinone and 35% of 2-sec. butyl anthraquinone; 80% of 2-isopropyl anthraquinone and 20% of 2tert. butyl anthraquinone; 70% of 2-sec. butyl anthraquinone and 30% of 2-tert. butyl anthraquinone; 20% of 2-ethyl anthraquinone, 45% of 2-isopropyl anthraquinone, and 35% of 2-sec. butyl anthraquinone; and 25% of 2-ethyl anthraquinone, 45% of 2-sec. butyl anthraquinone, and 30% of 2-tert. butyl anthraquinone. The solvent medium may comprise benzene, xylene, a -methyl naphthalene, anisole, methyl or butyl benzoate, a higher aliphatic alcohol, or an alkyl or aryl phosphoric acid ester. It may consist of 40% of a -methyl naphthalene and 60% of di-isobutyl carbinol. The catalyst may be Raney nickel. Hydrogenation may be effected at 30 DEG C. Table 2 and Examples 1 and 2 specify concentrations of alkyl anthraquinone and degrees of hydrogenation. Specification 465,070 is referred to.
