“…Nonetheless, hypothetical binodals at temperatures of 353.2 and 393.2 K were drawn. Margon et al [26] investigated the phase equilibrium in the CO 2 -phenol system. The experimental data obtained in the temperature range of 343-453 K at pressures up to 13.0 MPa, and the results of studying the solubility [27] of phenol in supercritical carbon dioxide, unambiguously indicate type V-VI of phase behavior with a discontinuous critical curve.…”

The extraction of valuable components (methyl phenyl carbinol, acetophenone, ethylbenzene, phenol, propylene glycol) from industrial wastewater formed during styrene-propylene oxide coproduction by the hydroperoxide method at PAO Nizhnekamskneftekhim was used as an example to formulate and discuss approaches to increasing the efficiency of the extraction process performed under supercritical fluid conditions beyond the binodal for the systems desired component-extractant with type I and II phase behavior. The assumptions were experimentally confirmed by studying the extraction of methyl phenyl carbinol and phenol from their aqueous solutions with such extractants as carbon dioxide in the liquid and supercritical fluid state and also a supercritical propane/butane mixture. The phase equilibrium of the thermodynamic system propane/butane-propylene glycol was experimentally investigated at 403, 423, and 443 K.

“…VLE and LLE prediction models have been developed by Schmelzer et al based on reported data. , In this paper, the authors provided a comparative analysis of VLE measurements reported in refs − for phenol + hydrocarbon (butane, n -heptane, n -octane, n -decane, and n -dodecane) systems, as well as to test suitable methods for the prediction of phase equilibria. The literature search has also revealed that there are several studies of the solubility of phenol in supercritical carbon dioxide, n -heptane, n -octane, and water. − Most of these studies reported the solubility of phenol in SC CO 2 . In general, the studies were carried out in a fairly wide range of temperatures from 309 to 363 K and pressures between 7 and 35 MPa.…”

The isothermal vapor−liquid equilibrium (VLE, pressure, temperature, and composition of coexisting vapor and liquid phases, PTxy) was directly determined using a high-pressure optical cell for binary propane + phenol and ternary tetracosane + propane/n-butane systems. Measurements were carried out at three selected isotherms of 383.15, 403.15, and 423.15 K at pressures from 0.94 to 14.5 MPa for propane + phenol and 403.15, 423.15, and 443.15 K at pressures up to 7.5 MPa for tetracosane + propane/n-butane systems. The critical property data (T C and P C ) for both mixtures have been derived from the measured VLE data. Based on the initial slopes of the critical lines (shape of the critical lines), the qualitative behavior (pure-and mixture-like behavior) of the isochoric heat capacity (C Vx , weak singular property), isobaric heat capacity (C Px ), and isothermal compressibility (K Tx , strong singular property) of the propane + phenol binary mixture near the critical point has been studied. It is demonstrated that the simplest version of critical point-based perturbed-chain statistical association fluid theory neglecting the complex molecular background of phenol yields reasonably accurate predictions of its pure compound properties. With the value of k 12 obtained by fitting the present data of propane + phenol, this model yields reliable predictions for VLE in the systems of other n-alkanes, benzene, carbon monoxide, and nitrogen.
