Abstract
A catalyst containing platinum on carbon as carrier for the catalytic oxidation of glyoxal to glyoxalic acid. Activity and selectivity of the catalyst can be considerably improved by modification with molybdenum and/or cerium.
Claims4
A catalyst containing platinum on carbon as carrier for the catalytic oxidation of glyoxal to glyoxylic acid, characterized in that the catalyst also contains molybdenum and/or cerium in addition as modifiers and that platinum is present, relative to the carrier, in an amount of 0.1 to 5.0, preferably 0.5 to 3.5% by weight and the weight ratio between the platinum and the molybdenum and/or cerium present at the same time is 1:1 to 1:20, preferably 1:1 to 1:5 and that platinum and molybdenum and/or cerium are finely distributed on the carrier.
