MESOXALIC See also:

ACID (dioxymalonic acid), (HO2C)2C(OH)2 or C3H406, is obtained by See also:hydrolysis of alloxan with baryta See also:water (J. v. See also:Liebig, See also:Ann., 1838, 26, p. 298), by warming caffuric acid with See also:lead acetate See also:solution (E. See also:Fischer, Ann., 1882, 215, p. 283), or, from See also:glycerin diacetate and concentrated nitric acid in the See also:cold (E. Seelig, Ber.,1891,'24,p.3471). It crystallizes in deliquescent prisms and melts with partial decomposition at 119–120° C. It behaves as a ketonic acid, being reduced in aqueous solution by See also:sodium See also:amalgam to tartronic acid, and also combining with phenylhydrazine and See also:hydroxylamine. It reduces ammoniacal See also:silver solutions. When heated with See also:urea to too° ,C. it forms See also:allantoin.
