Liquid-liquid equilibrium for ternary systems of ethyl acetate/isopropyl acetate + 2,2,3,3-tetrafluoro-1-propanol + water at 298.15, 318.15 K
文摘
LLE data of ethyl acetate/isopropyl acetate + 2,2,3,3-tetrafluoro-1-propanol + water were determined. The biphasic area decreased with the increasing of temperature. LLE data were correlated by the NRTL and UNIQUAC models. Distribution coefficients and selectivities were calculated. Isopropyl acetate shows higher extraction ability at the same composition range.
