| Zusammenfassung: | Decanedicarboxylic acid contaminated with other dicarboxylic acids is purified by treating with an aq. alkali soln. with at least 1/2 equiv. alkali rel. to dicarboxylic acids occurring as impurities, and separating the purified acid. Simple process which is also suitable for separation of large proportions of lower, esp. nonane- and octane-dicarboxylic acids. |
