HYDROGEN PEROXIDE PRODUCTION PROCESS AND REACTION CARRIERS FOR IMPLEMENTATION THEREOF Russian patent published in 2004 - IPC

FIELD: industrial inorganic synthesis. SUBSTANCE: process comprises working solution hydrogenation stage involving two types of reaction carriers: at least one carriers from group including 2-(1- methyl-3-pentenyl)antraquinone, 2-(4-methylpentyl)antraquinone and their diand tetrahydroantraquinone and at least one of 2-ethylantraquinone and 2- ethyltetrahydroantraquinone. Amount of carriers selected from the first group constitutes 5 to 95 mol % of the total amount of reaction carriers. As tetrahydroantraquinone derivative, 2-(4- methylpentyl)-betatetrahydroantraquinone is used. Hydrogenation is carried out at temperature from ambient temperature to 100 C, pressure 200 to 500 kPa in presence of catalyst: palladium black or suspension catalyst based of supported precious metal. Working solution contains two or more solvents, for example alkylated benzene, secondary alcohols, esters, urea derivatives, and pyrrolidone. Hydrogenation stage is followed by oxidation and then hydrogen peroxide isolation. EFFECT: increased productivity with regard to hydrogen peroxide, imp hydrogenation kinetics, reduced amount of catalyst, and stabilized continuous operation of process. 8 cl, 3 tbl, 8 ex
