Extractability of Fumaric Acid by Tributyl Amine (TBA) in Ketones and Alcohols

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.
