Abstract

Excess molar enthalpy HmE was measured, at atmospheric pressure and 298.15 K, for binary systems formed from mixtures of 2-heptanone, 2-nonanone, 4-heptanone and 5-non- anone with 3,6,9-trioxaundecane. The DISQUAC group contribution method for correlating and predicting the thermodynamic properties of liquid mixtures was used.Calculated results derived from the model are in agreement with experimental excess molar enthalpies.
