Abstract
1355394 Regeneration of anthraquinone working solution in H 2 O 2 production MITSUBISHI EDOGAWA KAGAKU KK 11 Aug 1971 [18 Aug 1970] 37767/71 Heading C1A [Also in Division C2] In a degraded working solution for the production of hydrogen peroxide by an autoxidation process employing an anthraquinone, the non-effective anthraquine is regenerated to effective anthraquinone by contacting the working solution containing more than 0À2 mole per litre of non-effective anthraquinone at below 130‹ C. with an olefinic compound in the presence of a catalyst comprising a metal of the platinum group supported on a carrier.
