High-pressure multiphase behaviour of ternary systems carbon dioxide–water–polar solvent: review and modeling with the Peng–Robinson equation of state

Furfural—A Promising Platform for Lignocellulosic Biofuels

“…Numerous papers report the possibility of separating binary mixtures of water and a water-miscible organic component into two liquid layers by expanding the liquid with a high-pressure gas such as CO 2 . [151,152] Water/furfural mixtures have been reported to separate by applying 5.5-6.0 MPa CO 2 . [153] We revisited this by using an autoclave that was equipped with an attenuated total reflectance crystal for in situ IR spectroscopy to identify and quantify the liquidliquid demixing.…”

High-pressure phase equilibrium of the ternary system carbon dioxide + water + acetic acid at temperatures from 313 to 353 K

“…The phase behavior of a ternary system can also be presented in a (p, T)-diagram by drawing critical lines and characterizing two-and three-phase regions. An overview of the fluid phase behavior of ternary systems consisting of a "near-or supercritical" gas like carbon dioxide, water, and a water-soluble low molecular organic solvent was given by Adrian et al [5] and Wendland [6]. Fig.…”

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

“…The reason was, that in previous work on high-pressure multiphase equilibrium of systems of carbon dioxide + water + an organic solvent it was shown that good correlations for the rather complex (multi-phase) high-pressure equilibrium of such systems can be achieved with the PR-EoS (Adrian et al [48]) and it seemed to be worthwhile to investigate if a successful extension to systems of (carbon dioxide + water + organic solvent + salt) might be possible. So, that in future work, both types of research might be more closely linked to each other.…”
