The extraction of lactic, tartaric, succinic, and citric acids from aqueous solutions by trioctylamine (TOA, R₃N) was investigated under various conditions. As a result, it was found that the concentration of acid in the organic phase increases with increasing aqueous acid concentration and this tendency is little influenced at different TOA concentrations. The log-log plots of distribution ratio vs. [TOA] revealed the following power dependence: 0.51 for lactic acid, 12 for tartaric and succinic acids, and 13 for citric acid. Hence the extraction of organic acids by TOA is expressed by the equilibrium equation H_nA_(ap)+ mR₃N_(org)_??_(R₃N)_mH_nA_(org) where n and m=1 for lactic acid, n=2 and m=12 for tartaric and succinic acids, and n=3 and m=13 for citric acid. The formation of the organic species is also supported by infrared spectral results. Moreover the temperature-dependence of distribution ratio indicates that the extraction of organic acids decreases with increasing temperature.
