The extraction of hydroxy succinic acid from an aqueous solutions into solutions of tri-n-octylamine and Alamine 336 in single solvents are hexane, cyclohexane, isooctane, toluene, and methylisobutyl ketone (MIBK) is investigated. Formation of acid amine complexes is a dominating factor in the system under consideration. Diluents are chosen from different chemical classes - polar and nonpolar- so as to examine the effect of diluents complex interactions. The distribution coefficients and loading factors are calculated and interpreted from experimental results.
