Multiphase equilibrium behavior of the mixture ethane + 1-decanol + n-docosane

Abstract

Patton, C.L. and Luks, K.D., 1993. Multiphase equilibrium behavior of the mixture ethane + 1-decanol + n-docosane. Fluid Phase Equilibria, 85: 181-190. The phase equilibrium behavior of the liquid-liquid-vapor (11g) region of the mixture ethane + 1-decanol + n-docosane was examined. This ternary system was studied experimentally using visual-cell stoichiometric techniques with pressure discrimination of ±0.01 bar, accomplished by using a cell pressure transducer in conjunction with a dead-weight gauge. The three-phase region was located between the 11g loci of the binary mixtures ethane + 1-decanol and ethane + n-docosane and bounded below by a lower critical end point (1 = 1−g) locus and above by an upper critical end point (1−1 = g) locus. Phase compositions and molar volumes are reported for the two liquid phases along the 298.15 and 304.15 K isotherms. Separabilities between the liquid phases of the two solutes are presented and discussed for the two isotherms.
