Total pressure measurements for the system of hexane and 2-ethoxyethanol were also made to check the validity of the experimental apparatus and procedure. These measurements were taken according to the static method proposed by Van Ness (1975). Data reduction was accomplished using Barker's Method. The modified Margules equation was used as a model for the excess Gibbs free energy (GE) and parameter values were obtained by regression of the experimental data. The obtained data were used to test the association model developed by Kretschmer and Wiebe (1967). In its original form, the Kretschmer-Wiebe model assumes self-association between molecules of 2-ethoxyethanol. / ABSTRACT: An extended form of the Kretschmer-Wiebe model, in which cross-association of 2-ethoxyethanol with the halogenated hydrocarbon is postulated, was examined as well. The regular solution model, which results from the above theories when all association is neglected, was also examined. It was found that the Kretschmer-Wiebe model was far superior to the regular solution model. However, the extended form of the Kretschmer-Wiebe model showed less improvement over the original form. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.
