We here experimentally visualize in situ temporally and spatially resolved composition concentration fields developing inside silica aerogels during the supercritical drying process. For extraction of pore liquid ethanol we used carbon dioxide. The evolution profiles gel was measured via one-dimensional Raman spectroscopy. were converted into using an equation state. shows that is continuously transported out gel. On contrary CO2 first at later times (before depressurization) structure....

Liquid−liquid equilibrium data for the ternary system 1-pentanol + 1-propanol water have been determined experimentally at (25, 50, 85, and 95) °C. The results correlated simultaneously by UNIQUAC method, obtaining a set of interaction parameters valid over temperature range experimental results.
Isobaric vapor−liquid and vapor−liquid−liquid equilibria were measured for the ternary system water + isopropanol (2-propanol) isooctane (2,2,4-trimethylpentane) at 101.3 kPa. The experimental determination was carried out in a dynamic equilibrium still, with circulation of both vapor liquid phases equipped an ultrasonic homogenizer. data demontrated existence heterogeneous azeotrope 70.9 °C composition 0.31, 0.38 mole fraction water, isopropanol, isooctane, respectively.

ABSTRACT Solubility and liquid-liquid phase equilibrium data have been determined for the ternary systems Water-Phosphoric Acid-Di-n-propyl Ether as supplied by Merck (with about 6.4% of isomer propyl-isopropyl ether), (rectified up to less than 1% at 25 40°C The temperatures which three liquid phases appeared were 28.0-28.2°C 49.0-50.0°C, respectively. presence ether causes these split into
Liquid−liquid equilibrium data for the quaternary system water−ethanol−2-ethylhexanol−sodium chloride have been determined experimentally at 25 °C. The obtained make it possible to carry out design calculation of a proposed suitable extraction process separating ethanol and water using 2-ethylhexanol as solvent when sodium is added. analysis shows that advantages salt addition offers recovery are presently limited.
