The 3-phase liquid-liquid-vapor loci of 4 binary CO/sub 2/-n-paraffin systems (n-dodecane, n-tridecane, n-tetradecane, n-pentadecane) are studied, and temperature, pressure, and molar volumes and composition of both liquid phases are reported. It is within this group of n-paraffins that the nature of the upper critical end point for the CO/sub 2/-containing binary systems changes with increasing carbon number from an upper critical solution (temperature) point where L/sub 1/ and L/sub 2/ phases become critical in presence of vapor phase to a K point, where L/sub 2/ and vapor phases become critical in the presence of L/sub 1/ phase. These 4 loci are compared with earlier obtained loci on CO/sub 2/-n-decane and CO/sub 2/-n-elcosane.
