EXCESS THERMODYNAMIC FUNCTIONS FOR LIQUID MIXTURES OF METHANE+PROPANE,
Abstract
The vapor pressures and heat capacities of liquid mixtures of methane+propane and the heats of vaporization of methane from the mixtures have been measured in the temperature range 90 to 110K. The experimental data have been used to obtain the activity coefficients of methane, the excess Gibbs energy, the heat of mixing and the excess heat capacity. The results are compared with the quasi-lattice theory of liquid mixtures of molecules of different size and with the consequences of the principle of corresponding states applied to liquid mixtures of chain molecules. The theoretical treatments yield values of the excess Gibbs energy and the heat of mixing which are in good agreement with experiment, but the agreement is less satisfactory for the excess heat capacity.
