摘要：
It is discovered that under the same conditions the distribution coefficient of oxalic acid D decrease with different diluents in the order of aromatic hydrocarbon, alkane, halogenated hydrocarbon. This order is independent of the concentration of extractant in the organic phase. For the salting-out agents used in extraction of oxalic acid, the effect has the following order: MgCl2>NaCl>KCl. D decreases and then increases with increasing concentration of salting-out agents in the aqueous phase, and the minimum D appears at 0.5-1.0 mol/L.
