ABSTRACT
Mandelic acid an alpha hydroxycarboxylic acid found in the content of bitter almonds. It has gained importance in recent years, especially due to its use in the cosmetic industry. Separation processes of the mandelic acid have a critical point in the production stages with respect to reach the product form. In this study, extraction of the mandelic acid from aqueous solutions was carried out using five different concentrations of Amberlite LA-2 (secondary amine mixtures) solution. Dimethyl phthalate (DMP), methyl isobutyl ketone (MIBK), 2-octanone, 1-octanol, n-pentane, octyl acetate and toluene were used as diluents in the organic phase. The batch extraction results of the mandelic acid were obtained for a process design. The data were analyzed with respect to loading factor (Z), distribution coefficient (D) and extraction efficiency (E%). In addition, the overall extraction constants, K11, K12, K23 have been determined for acidamine complex.
