Abstract: 1,193,205. Removal of Pd compounds from aq. glyoxal solutions. BADISCHE ANILIN- & SODA-FABRIK A.G. 4 Oct., 1967 [5 Oct., 1966], No. 45187/67. Heading C2C. [Also in Division C1] Glyoxal, obtained by the oxidation of ethylene using nitric acid in the presence of palladium compounds, is purified by removal of the Pd compounds using an anion exchange resin. It is preferable to remove other organic impurities which boil below 100‹ C. prior to treatment with the anion exchange resin. The exchange resin preferably has quaternary ammonium groups and is intimately mixed with the aqueous solution by passing the solution down a column of resin having a particle size of from 0À1 to 1 mm. at a temperature between 0‹ C. and 80‹ C., preferably room temperature. The column may be regenerated with nitric acid and the resulting Pd-containing nitric acid may be reused in the oxidation.
