Abstract
The extension of Guggenheim's Quasi-Chemical Theory in terms of groups proposed by Kehiaian, Grolier and Benson is discussed in terms of the non-random factors defined by Panayiotou and Vera. It is shown that the non-random factors correspond to a first neighbor's approximation of a step function radial distribution with a square-well potential. The variation of the coordination number from system to system is removed and a new method for the evaluation of the structural parameters, based on group connectivity, is proposed. Group interaction parameters have been determined from g E and H E values for hydrocarbon—hydrocarbon and hydrocarbon—alcohol systems. Results of correlation and prediction are compared with those of ASOG, SIGMA and UNIFAC methods.
