Abstract :In this study, the removal of glycolic acid from aqueous solutions by using reactive extraction with different organic solvents and tripropylamine mixtures was investigated. In experimental studies, methyl isobutyl ketone insert ignore into journalissuearticles values(MIBK);, 1-decanol, toluene, cyclohexyl acetate insert ignore into journalissuearticles values(CHA);, DMP and an ionic liquid, namely 1-butyl-3-methylimidazolium hexafluorophosphate insert ignore into journalissuearticles values(IL);, were chosen as the diluent solvent in the organic phase. In recent chemistry researches, IL compounds have come to the foreground due to their superior properties and environmentally friendly chemical structures and they are being used intensively. For this reason, it is particularly aimed to compare the efficiency of the IL compound with other solvents. In addition to the solvent effect, the amine concentration used was changed to determine the effect on extraction yield. Using the obtained data, the most important parameters for the design of reactive extraction processes were calculated: Distribution coefficient insert ignore into journalissuearticles values(D);, loading factor insert ignore into journalissuearticles values(Z);, and the percentage of extraction efficiency insert ignore into journalissuearticles values(E%);. The maximum removal of glycolic acid has been achieved as 99.76 % with IL and 1.75 mol L -1 initial amine concentration.
