The extraction of quinic acid was studied by using an amine extractant with respect to the functional groups of the diluents. All experiments were reported on the extraction of quinic acid by tridodecylamine (TDA) dissolved in two different acetates (ethyl acetate and hexyl acetate), two different alcohols (octan-1-ol and decan-1-ol), and two different ketones (heptan-2-one and octan-2-one), as well as single solvents. The experimental results of extraction experiments are reported as distribution coefficients (K(D) = (C*(PA)/C(PA))), loading factors, Z, and the extraction efficiency, E. The recovery problem has been reduced by using an amine as an extractant in different diluents. The addition of the extractant was found to improve the extraction.
