| Abstract: | The extraction of some dicarboxylic acids (ethanedioic, propanedioic, butanedioic and he-xanedioic acid) with TBP and MIBK were studied. The orders of the extraction of the acids are: hexanedioic > butanedioic > propanedioic > ethanedioic acid. The results show that the cavity effect, dipole-dipole interactions and hydrogen-bonding forces in orgaric phase are the factors influencing the extraction equilibrium. The effect of diluent, temperature and inorganic salt on the extraction equilibrium were also investigated. |
