Thermodynamic and transport properties for polar coal mixtures. Technical progress report, January 1-March 31, 1986. [And in diphenylmethane]
During this period values of the infinite dilution activity coefficient, ..gamma../sub 1//sup infinity/, have been measured for nonpolar and polar solutes in quinoline for 25 to 80/sup 0/C and in diphenylmethane for 60 to 70/sup 0/C. The data have been compared with values presented in the literature for these solvents. The experimental data are also being utilized in conjunction with the analytical procedures being developed in this investigation for the determination of the phase behavior of polar coal mixtures from the parameters of the components. Measurements were made with Chromosorb W Acid Washed substrate and the less polar support Chromosorb W DMCS. Comparable results were obtained for the two supports to within the experimental error. In Figure 1 to 4 values of ln ..gamma../sub 1//sup infinity/ are plotted against 1/T for the representative solutes n-hexane, acetone, ethyl acetate, and benzene. For n-hexane the experimental values of ..gamma../sub 1//sup infinity/ have only a slight temperature dependence for this range and are in closer agreement with the values of Desty and Swanton than that of Thomas et al. For the polar solutes acetone and ethyl acetate, the values of ..gamma../sub 1//sup infinity/ decrease slightly with decreasing temperature, as shown in Figures 2 and 3. The extrapolated values for these solutes are in agreement with the values of Thomas et al. at 20/sup 0/C. For benzene, the experimental values from this study are intermediate to the values presented by other investigators. 6 refs.
