ABSTRACT:
Improved process for preparing glyoxylic acid by oxidizing glyoxal with nitric acid at a concentration of 4 to 10% by weight of nitric acid based on the weight of the reaction system, introducing oxygen or oxygen-containing gas into the reaction system so as to satisfy a relation K.sub.L a.P.gtoreq.150, wherein K.sub.L a is a liquid-phase over-all mass transfer coefficient of the reactor (1/hour) and P is a partial pressure of oxygen in the reaction system (kg./cm..sup.2). Glyoxylic acid can be prepared in high yields with less consumption of nitric acid and the generation of nitrogen oxides can be remarkably decreased.
