Thermodynamic consistency test of vapor-liquid equilibrium data

Guidelines for reporting of phase equilibrium measurements (IUPAC Recommendations 2012)

“…The approach used involves application of four widely used tests of consistency that are based on restrictions following from the Gibbs-Duhem equation (commonly known as the Herington Test [64,65], Van Ness Test [66,67], Point Test [65,68], Infinite Dilution Test [65,68]), as well as a test for consistency between the VLE data and evaluated vapor pressures of the pure components. This last test also provides a simple validity check for (T, p, x) VLE data, where tests based on the Gibbs-Duhem equation do not apply.…”

Vapor-Liquid Equilibrium of MTBE-Methanol, MTBE-Methanol-Calcium Chloride and MTBE-Methanol-Lithium Chloride Mixtures

“…1, as a T-x-y diagram. These data show The thermodynamic consistency of the experimental data of this study was examined by the infinite-dilution test of Kojima et al [21] as modified by Jackson and Wilsak [22] and the integral test as modified by Herington [23]. The infinite dilution test of Kojima-Jackson-Wilsak involves the calculation of the excess Gibbs energy from the experimental data and then extrapolation to the infinite dilution.…”

Evaluation of thermodynamic consistency of isobaric and isothermal binary vapor–liquid equilibrium data using the PAI test II, alcohol+n-alkane, +aromatic, +cycloalkane systems

“…Recently, we reported the results of a TC test, called the PAI test, which had been proposed in our earlier papers [2,3], for four miscible alcohol (methanol, ethanol, propanol, 2-propanol) + water systems (169 data sets) at constant pressure and under isothermal conditions, and one partially miscible 2-butanone + water system (11 data sets) under standard atmospheric conditions [4]. The PAI test can make an overall check of VLE data by combining the following three tests: (i) the point * Corresponding author.…”
