dc.description.abstractLevulinic acid, a carboxylic acid containing ketone structure, is a clear to brownish semi-solid melting at 37 degrees C; soluble in alcohol, ether, and chloroform, levulinic acid can be used as an acidulant in foods and beverages. Organic solutions of amines are being used increasingly to separate organic acids from aqueous mixture solutions by reactive extraction. The design of an amine extraction process requires kinetic data for the acid-amine+solvent system used. Kinetic studies for the extraction of levulinic acid from aqueous solution with tripropylamine (TPA) diluted in toluene were carried out using a stirred cell for kinetic studies. Equilibria for levulinic acid extraction by TPA in toluene as a diluent have been determined. All measurements were carried out at 298.15K. The equilibrium data were also interpreted by a proposed mechanism of complexation by which (1:1) and (2:1) acid-amine complexes are formed. Kinetics of extraction of levulinic acid by TPA in toluene has also been determined. The results of the liquid-liquid equilibrium measurements were correlated by a linear solvation energy relationship (LSER).en_US
