摘要：

Excess molar enthalpies and volumes for the mixtures of benzonitrile + acetic acid, propanoic acid, butanoic acid, 2-methylpropanoic acid, pentanoic acid or 3-methylbutanoic acid at T = 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. (C) 2002 Elsevier Science B.V. All rights reserved.
