| 1857 H. Debus in Phil. Mag. 4th Ser. XIII. 40 This residue consisted almost entirely of the aldehyde of glyoxylic acid; I propose to call it Glyoxal, C2H4O3. 1858 Fownes' Man. Chem. (ed. 7) 467 By treating ethylic alcohol with nitric acid, M. Debus has obtained two compounds—an aldehyde-like body, glyoxal, and an acid, glyoxalic acid, which obviously belong to the same series. 1869 Roscoe Elem. Chem. xxxiii. 335 Glyoxal stands in the relation of an aldehyde to Glycol. |
