Excess Enthalpies of the Ternary Mixtures:  Tetrahydrofuran + (Hexane or Cyclohexane) + Decane at 298.15 K

Abstract

Excess molar enthalpies, measured at 298.15 K in a flow microcalorimeter, are reported for tetrahydrofuran + hexane + decane and for tetrahydrofuran + cyclohexane + decane. Smooth representations of the results are described and used to construct constant excess molar enthalpy contours on Roozeboom diagrams. The latter are compared with diagrams obtained when the model of Liebermann and Fried is used to estimate the excess molar enthalpies of the ternary mixtures from the physical properties of the components and the excess molar enthalpies of their binary mixtures.

Excess enthalpies of binary mixtures of 1-hexene with some branched alkanes at the temperature 298.15 K

“…The Redlich-Kister smoothing function [5,6], it was found that the LiebermannFried model [7,8], can be useful in representing the excess enthalpies of binary mixtures, and also has the potential for estimating the vapour-liquid equilibria of mixtures and the excess enthalpies of ternary mixtures, from data for the pure components and their binary mixtures. This approach was useful in the recent consideration of (1HX + n-alkane) mixtures [1]. It is therefore of interest to examine how well the Liebermann-Fried model can represent the results for the present systems.…”

“…Recently, we reported excess molar enthalpies at T ¼ 298:15 K, for binary mixtures of 1-hexene (1HX) with a series of n-alkanes [1]. As a continuation of that study we have made similar measurements for binary mixtures of 1HX with the branched alkanes: 2-methylpentane (2MP), 3-methylpentane (3MP), 2,2-dimethylbutane (22DMB), 2,3-dimethylbutane (23DMB), and 2,2,4-trimethylpentane (TMP).…”

Green Synthesis of a New Al‐MOF Based on the Aliphatic Linker Mesaconic Acid: Structure, Properties and In Situ Crystallisation Studies of Al‐MIL‐68‐Mes

“…An analogue of MOF‐5 incorporating mesaconic acid was also reported . Despite this scarce use in MOF chemistry, mesaconic acid can be considered a promising organic building block for the green synthesis of MOFs, especially since a biosynthetic pathway for its production from glutamate in water was already described …”
