TL;DR: In this paper, the vapor pressures of (monoethanolamine (MEA) + water and (4-methylmorpholine + water) and of all the pure components were measured by means of two static devices at temperatures between (283 and 363) K. From these data, excess Gibbs functions were calculated for several constant temperatures and fitted to a fourth-order Redlich−Kister equation using Barker's method.
Abstract: The vapor pressures of (monoethanolamine (MEA) + water) and (4-methylmorpholine + water) and of all the pure components were measured by means of two static devices at temperatures between (283 and 363) K The data were correlated with the Antoine equation From these data, excess Gibbs functions were calculated for several constant temperatures and fitted to a fourth-order Redlich−Kister equation using Barker’s method The (4-methylmorpholine + water) binary system shows maximum azeotropic behavior over the whole temperature range The (MEA + water) binary mixture exhibits negative deviations in GE, whereas for the (4-methylmorpholine + water) system, the excess Gibbs energy is positive for all investigated temperatures over the whole composition range

TL;DR: A novel procedure is developed to obtain the thickness of liquid-vapor interfaces as a function of composition in binary systems by combining a model for the description of surface tension of liquid mixtures with a group contribution method for the calculation of activity coefficient.

Abstract: The phase equilibria and thermodynamic properties of the binary Co-Ta system were analyzed and a complete thermodynamic description of the binary system was obtained with the CALPHAD technique using a computerized optimization procedure. The thermodynamic descriptions of pure Co and Ta elements were taken from the SGTE database. Based on the experimental data, six binary intermetallic compounds were considered. They are three Laves phases, μ phase, θ phase and Co 7 Ta 2 phase. The last two compounds are treated as stoichiometric compounds. Good agreement was obtained between calculated results and experimental data in the binary system.
