The reactive extraction equilibria for aqueous solutions of glutaric acid, with trioctylmethyl ammonium chloride (Aliquat 336) in various diluents, including 3-methyl-butan-l-ol, octan-1-ol, nonan-1-ol, decan-1-ol, methyl ethyl ketone, 2,6-dimethy1-4-heptanone, hexan-2-one, toluene, kerosene, and hexane, were determined at various Aliquat 336 (A336) concentrations. Experimental results of batch extraction experiments are calculated and reported as distribution coefficients (K-D), loading factors (Z), and extraction efficiency (E). All measurements were carried out at 25 degrees C. 2,6-Dimethyl-4-heptanone was found to be the most effective diluent with the highest value of K-D (8.51) for the glutaric acid + Aliquat 336 extraction system. The effect of pH has been investigated for octan-1-ol + A336 on glutaric acid extraction in the range of pH 2 to 8. The linear solvation energy relationship (LSER) model has been used to fit the experimental data.
