Thermochemical investigations of some 2-propanone-tribromomethane-alkane ternary non-electrolytic solutions

Abstract

Moelywyn-Huggins concept of interactions between the molecular surfaces of the components of a binary mixture [Huggins M L, <em>Polymer, </em>12 (1971) 389] has been extended to develop an approach reproduces well the molar excess volume <em>V</em>^E and molar excess enthalpy <em>H</em>^E data of 2-propanone- tribromomethane-<em>n</em>-alkane ternary and their sub-binary mixtures. The ternary <em>V</em>^F and <em>H</em>^E data, calculated by the present approach, co pare better with their corresponding experimental values the corresponding <em>V</em>^E and <em>H</em>^E data evaluated for these mixtures by the more involved non-electrolyte associated solution model approach.
