Abstract

Fumaric acid extraction from aqueous media by tributyl amine (TBA), which is an aliphatic amine, was studied at 298 K. Ketones (methyl isobutyl ketone (MIBK), heptan-2-one, octan-2-one) and alcohols (isoamyl alcohol, octan-1-ol, decan-1-ol) were selected as the diluent for dissolving TBA. Distribution ratio (K-D), loading ratio (T), and extraction degree (D-E) were calculated from experimental results. 96% efficiency was reached with isoamyl alcohol at 2.08 mol.kg(-1) of TBA concentration. Futher, the linear solvation energy relationship (LSER) modeling cooperated with Hidebrand-Hansen solubility parameters was used for prediction KD of alcoholic diluents. The LSER model gave closeness prediction to experimental data.
