Resumen/Abstract:

The purpose of this paper is to present a general quasichemical theory in terms of group surface interactions, and to calculate the excess molar enthalpy of mixtures of ketones and diether (1,2-dimethoxyethane). The model used in this paper, DISQUAC (Dispersive-Quasi-chemical model), is a simple extension of Guggenheim-Barker quasi-lattice theory. Calculated results derived from the model are in good agreement with experimental excess molar enthalpies for all the systems investigated. Possible sources of discrepancy and ways of refining the model are discussed.
