Thermodynamic and transport properties for polar coal mixtures. Technical progress report, October 1-December 31, 1985
Additional measurements of the infinite dilution activity coefficient have been conducted for nonpolar and polar solutes in coal liquids. The temperature ranges considered were extended for several solutes with tetralin, including ethanol and n-propanol. Values of infinite dilution activity coefficients were also measured for m-cresol systems for temperatures from 50 to 80/sup 0/C. The results are presented in Table I for a number of solutes at 60/sup 0/C. It can be seen that the activity coefficients for polar solutes with m-cresol are less than 1.0, indicating strong molecular interactions for these systems. For n-hexane, carbon tetrachloride, and cyclohexane with m-cresol, the values of infinite dilution activity coefficient show only small dependences on temperature in the range of 50 to 80/sup 0/C. Measurements are also being obtained for non-polar and polar solutes in quinoline. Preliminary values for these systems at 60/sup 0/C are presented in Table I. An improved relationship for the latent heat of vaporization lambda of polar fluids is being developed which will aid in the establishment of accurate characterization parameters for coal liquids. 10 refs., 8 figs., 1 tab.
