Abstract

In the production of hydrogen peroxide wherein an alkylated anthraquinone intermediary is hydrogenated in solution in the presence of a catalyst to produce the corresponding anthrahydroquinone and the latter is oxidized to produce hydrogen peroxide and to regenerate the alkylated anthraquinone which is recycled, the anthraquinone intermediary is 2 tertiarybutyl anthraquinone, preferably in admixture with tetrahydro-2-tertiary-butylanthraquinone, for example 10-40 per cent thereof. A suitable solvent medium for the quinone and hydroquinone form of the intermediary is 25-75 per cent mixture by volume of primary or secondary nonyl alcohols such as di-isobutylcarbinol or 3.5.5 trimethylthexanol-1, and a mono or dimethyl naphthalene, particularly a methyl naphthalene, such solvents being disclosed in Specification 686,567. The reduction of the anthraquinone is preferably effected in the presence of activated alumina-supported palladium catalyst as disclosed in Specification 686,574. Hydrogenation temperature of 20 to 40 DEG C and oxidation temperatures of 30-60 DEG C may be employed. Specification 465,070 also is referred to.
