Detailed phase behavior of four ternary systems were studied in the region of immiscibility. These systems were the methane-ethane-n-octane, methane-propane-n-octane, methane-n-butane-n-octane and methane-carbon dioxide-n-octane. Two liquid phases and a vapor phase (L/sub 1/-L/sub 2/-V) were found to exist in all of these systems in a region extending from 193.5/sup 0/K and 45.0 atm to approximately 222/sup 0/K and 72 atm. Pressure and liquid phase composition and liquid phase molar volume data for both of the coexisting liquid phases were measured. Smoothed data are presented as a function of temperature and pressure. The immiscibility areas were found to be bounded by loci of K points (L/sub 1/-L/sub 2/ = V), Q points (S-L/sub 1/-L/sub 2/-V) and LCST points (L/sub 1/ = L/sub 2/-V).
