Experimental measurement of vapor-liquid equilibrium in alcohol/water/salt systems

Theoretical and experimental study of mixed solvent electrolytes. Final report, July 1, 1988--December 31, 1991

“…In Figure 2, the GEMC results for vapor liquid equilibrium in salt free methanol/water and salt-containing methanol water systems is shown in the form of a g -x plot. The agreement with experiment for the salt-free case is very good; for the salt-contaiaing simulations, methanol is salted out (as is observed experimentally) though tlm simulations tend to 16 lead to a higher salting coefficient ks 1°, li than is observed in experiment '. It is clear that our goal of api)lying molecular simulation techniques to the study of pha.se equilibria in electrolyte systems has been a outstanding success to (late and stands as one of the We expect to pursue this effort even more vigorously in the future.…”

“…The development of theories of the salt effect demands vapor-liquid equilibrium data over the whole range of salt concentration (salt free to saturation) in order for there to be a meaningful comparison of theory and experiment. In order to develop a collection of vapor-liquid equilibrium data on mixed solvent systems spanning the full salt concentration range, experimental measurements have been performed in the Department of Chemical Engineering at the University of Virginia for several years under the direction of Randall L. Perry (now with DuPont) and the author 16 The specific systems studied to date are H20-KCl-methanol, H20-KBr-methanol, H20-NaCl-methanol, I[20-NaBrmethanol, tt20-KBr-l-propanol, H20-NaCl-l-propanol, H20-NaBr-l-propanol and It.20-NaBr-2-propanol. The choice of systems is designed to isolate the effect of specific cations and anions (as in the methanol series of experiments) and the contribution of methyl and methylene groups in the alcohol.…”

An extension of the Peng–Robinson equation of state for the correlation and prediction of high-pressure phase equilibrium in systems containing supercritical carbon dioxide and a salt

“…Some literature sources report experimental results for the influence of sodium chloride on the vapor-liquid equilibrium of the system water + methanol [63][64][65][66][67][68]. Fig.…”

The remarkable effect of organic salts on 1,3,5-trioxane synthesis

“…In the present VLE experiments, a modified Othmer still was used as described by Morrison et al (1990). The Othmer still was operated at atmospheric pressure (101.3 kPa).…”
