Özet

Liquid-liquid equilibrium measurements for the systems diethyl phenylmalonate + acetic acid + water and diethyl methylmalonate + acetic acid + water were made at 294, 298, and 308 K. The mole fraction composition along the binodal curves was fit to a correlation equation, and tie-line results were fit by the Bachman, Hand, Othmer-Tobias, and selectivity methods. We conclude that diethyl phenylmalonate and diethyl methylmalonate can be used as solvents for extracting acetic acid from its aqueous solutions.
