TLDR
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 rangeread more

Solvent selection and design for CO2 capture – how we might have been missing the point
TL;DR: In this article, the authors present a new methodological approach for sorbent screening which explicitly includes rate-based phenomena, and identify the minimum set of thermophysical and kinetic parameters which must be reported in order to justify the claim of adequacy for a new sorbent for CO2 capture in particular and gas separations in general.

Investigation of the isothermal (vapour+liquid) equilibria of aqueous 2-amino-2-methyl-1-propanol (AMP), N -benzylethanolamine, or 3-dimethylamino-1-propanol solutions at several temperatures
TL;DR: In this article, the authors measured the vapour pressure of pure AMP and 3dimethylamino-1-propanol components at temperatures between 283 K 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 the Barker's method.

Determination of Activity Coefficients from total pressure measurements
TL;DR: In this paper, a method of least squares is described for calculating activity coefficients from results of total vapour pressure measurements, and a method for computing activity coefficients is proposed for calculating the activity coefficient from the results of a single measurement.
