Abstract

Data on vapor-liquid equilibrium and enthalpy of mixing HE are, obtained for the mixture 1, 3 dioxolane-methylcyclohexane at 313.15 K (40.0°C). Correlation of the data is given by using Redlich-Kister expressions and the excess functions GE = RT(X1 In γ1 + X2 In γ2) and TSE = HE - GE are thereby calculated. A comparison is made between this mixture and those formed by 1, 3 dioxolane with cyclohexanol and cyclohexanone.

Abstract

On a obtenu des données sur l'équilibre liquide-vapeur et l'enthalpie de mélange HE pour le mélange de composition 1,3-dioxolane-méthylcyclohexane à 313,15 K (40°C). Les données sont corrélées à l'aide des expressions de Redlich-Kister, à partir desquelles les fonctions d'excès GE = RTX1 In γ1, + X2 In γ2) et TSE = HE - GE sont calculées. On établit une comparaison entre ce mélange de composition et les mélanges 1,3-dioxolane formés avec du cyclohexa-nol et du cyclohexanone.
