Abstract
510,057. Oxalic acid. ZJEDNOCZONE FABRYKI ZWIAZKOW AZOTOWYCH W MOSCICACH I.W. CHORZOWIE. Sept. 5, 1938, No. 25898. Convention date, Sept. 8, 1937. [Class 2 (iii)] Oxalic acid is prepared by the oxidation of carbohydrates with nitric acid under reduced pressure and/or with simultaneous passing of gases, indifferent to the reagents, through or over the reaction liquid, which may be simultaneously boiled. In the examples molasses are oxidized with nitric acid in the presence of vanadium pentoxide (1) under vacuum or (2) with passage of nitrogen through the reactants. Nitric acid is added during the reaction.
