摘要
The excess molar enthalpies for the 2-butanol + water and methanol + cyclohexane systems with limited miscibility were measured at 283.15, 288.15 and 298.15 K using a flow microcalorimeter. The experimental data were correlated by the modified Redlich-Kister equation and the three local-composition (LC) models (NRTL, modified Wilson and EBLCM). These LC models were also examined for predicting the liquid-liquid solubility for both systems using the parameters obtained from the excess enthalpy data. (C) 1998 Elsevier Science B.V.
