    Abstract: The invention concerns a process for the preparation of hydrogen peroxide by the anthraquinone cyclic process, which includes a regeneration stage in which working solution is regenerated by being brought into contact with an aqueous solution containing an alkyl anthrahydroquinone and/or an alkyl tetrahydroanthrahydroquinone in deprotonated form. The working solution regenerated in the regeneration stage is returned to the cyclic process.

    Abstract: A cyclic anthraquinone process for producing hydrogen peroxide using at least two differently substituted 2-alkylanthraquinones and/or their tetrahydro derivatives. The working solution to be used contains (i) at least one reaction carrier from the series 2-(4-methyl-3-pentenyl) anthraquinone (IHEAQ), 2-(4-methylpentyl) anthraquinone (IHAQ) and their di- and tetrahydro derivatives such as, in particular 2-(4-methylpentyl)- beta -tetrahydroanthraquinone (THIHAQ), and (ii) at least one reaction carrier from the series of the 2-(C1- to C5)-alkylanthraquinones, especially 2-ethylanthraquinone (EAQ), and their tetrahydro derivatives. The reaction carriers according to (i) make up 5 to 95 molar %, especially 20 to 50 molar % of all reaction carriers. The method is distinguished by greater H2O2 capacity, improved hydrogenation kinetics and lesser susceptibility to disturbances. A method for making THIHAQ is also disclosed.

    Abstract: The invention relates to the anthraquinone cycle for producing hydrogen peroxide using at least two differently substituted 2-alkylanthraquinones and/or their tetrahydro derivatives. According to the inventive method, the working solution to be used contains i) at least one reaction carrier from the series: 2-(4-methyl-3-pentenyl)-anthraquinone (IHEAQ), 2-(4-methylpentyl)-anthraquinone (IHAQ) and their di- and tetrahydro derivatives, such as especially, 2-(4-methylpentyl)- beta -tetrahydroanthraquinone (THIHAQ); and ii) at least one reaction carrier from the series of the 2-(C1- to C5)-alkylanthraquinones, especially 2-ethylanthraquinone (EAQ), and their tetrahydro derivatives, the reaction carriers according to i) making up 5 to 95 mol. %, especially 20 to 50 mol. % of all of the reaction carriers. The method is characterised by a greater H2O2 capacity, better hydrogenation kinetics and low susceptibility to failure. THIHAQ is also a novel substance.
