The TOA was dissolved in five different esters (dimethyl phthalate, dimethyl adipate, dimethyl succinate, dimethyl glutarate. and diethyl carbonate), five different alcohols (isoamyl alcohol, hexan-1-ol, octan-1-ol, nonan-1-ol, and decan-1-ol) and two different ketones (diisobutyl ketone (DIBK) and methyl isobutyl ketone (MIBK)). The results are reported as distribution coefficients (K-D), loading factors (T-T), stoichiometric loading factor (T-S), separation factor (S-f) and extraction efficiency (E). The most effective solvent was determined as isoamyl alcohol with a distribution value coefficient of 17.811. The maximum values of equilibrium complexation constants in isoamyl alcohol for (acid:amine) (1:1) K-11 and (2:1) K-21 were 9.9 and 225.6, respectively. A linear solvation energy relationship (LSER) was accurately regressed to the experimental distribution coefficients. (C) 2009 Elsevier B.V.
