Thermodynamic and transport properties for coal mixtures. Technical progress report, January 1, 1985-March 31, 1985. [Methyl ethyl ketone, methyl acetate, ethyl acetate]
During this period, additional progress has been made on the development of procedures for the calculation of the thermodynamic and transport properties of polar coal mixtures. Experimental data have also been obtained on infinite dilution activity coefficients of polar systems by gas chromatographic procedures. In Figure 1, experimental molar volumes for the ammonia-methane system with x/sub NH/sub 3// = 0.3284 are compared with the values calculated with the equation of state of Wu and Stiel with parameters T/sub CM/, P/sub CM/, ..omega../sub M/, and Y/sub M/ determined from the parameters of the components. It can be seen that good agreement is obtained by this procedure. The analytical procedures have also been extended to polar-polar systems. In Figure 2, calculated bubble point pressures for the acetone-methyl ethyl ketone system at several temperatures are shown to agree closely with experimental values for the entire temperature range. Experimental values of infinite dilution activity coefficient have been obtained by gas chromatographic procedures for polar solutes including acetone, methyl ethyl ketone, methyl acetate, ethyl acetate, and n-propyl alcohol in n-decane for temperatures from 50 to 60/sup 0/C. 4 refs., 5 figs., 1 tab.
