THERMOCHEMICAL INVESTIGATIONS OF SOME 2-PROPANONE-TRIBROMOMETHANE-ALKANE TERNARY NONELECTROLYTIC SOLUTIONS

Moelywyn-Huggins concept of interactions between the molecular surface s of the components of a binary mixture [Huggins M L, Polymer, 12 (197 1) 389] has been extended to develop an approach that reproduces well the molar excess volume V(E) and molar excess enthalpy H(E) data of 2- propanone-tribromomethane-n-alkane ternary and their sub-binary mixtur es. The ternary V(E) and H(E) data, calculated by the present approach , compare better with their corresponding experimental values than the corresponding V(E) and H(E) data evaluated for these mixtures by the more involved nonelectrolyte associated solution model approach.
