摘要：
Excess molar enthalpies and excess molar volumes for mixtures of(acetonitrile + acetic acid or propanoic acid or butanoic acid or 8-methylpropanoic acid or pentanoic acid or 3-methylbutanoic acid) at 298.15 K are presented. The excess molar enthalpy values are found to be positive for all six systems, whereas the excess molar volumes are found to be negative. The excess molar enthalpy values are correlated by the UNIQUAC and NRTL models and also by the Redlich Kister polynomial.
