| Abstract | Continuous manufacturing process for an aqueous solution of glyoxylic acid by nitric oxidation of an aqueous solution of glyoxal carried out in the presence of hydrochloric acid in which the oxidation is effected continuously using 0.80+/-0.2 mole of nitric acid and 0.70+/-0.05 mole of hydrochloric acid per mole of glyoxal in a reaction medium having a concentration by weight between 5 and 6% of hydrochloric acid and higher than 10% of nitric acid. |
