PROCESS FOR THE PREPARATION OF HYDROGEN PEROXIDE BY THE ANTHRAQUINONE CYCLIC PROCESS

摘要

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.
