Reactive extraction of malic acid was studied at 298 K. Experimental data on extraction of malic acid by Amberlite LA-2 dissolved in five different esters (dimethyl phthalate, dimethyl adipate, dimethyl succinate, dimethyl glutarate, diethyl carbonate), five different alcohols (isoamyl alcohol, hexan-1-ol, octan-1-ol, nonan-1-ol, decan-1-ol) and two different ketones (diisobutyl ketone (DIBK), methyl isobutyl ketone (MIBK)) were reported as distribution coefficients (K-D), loading factors (T-T), stoichiometric loading factors (T-S), separation factors (S-f) and extraction efficiencies (E). Isoamyl alcohol was found to be the most effective diluent with a maximum distribution value (K-D) of 83.807. The LSER model was found to correlate the experimental data satisfactorily.
