Physics and Chemistry of Liquids, 2003Co-Authors: Hugo Segura, Jaime Wisniak, Andrés Mejía, Ricardo Reich, Sonia LorasAbstract:Vapor-liquid equilibrium data have been determined at 50 kPa for the binary systems Oxolane (THF) + ethyl 1,1-dimethylethyl ether (ETBE) and Oxolane + 2-propanol, and at 94 kPa for the system propan-2-one + trichloromethane. Excess volumes have also been determined from density measurements at 298.15 K. The systems Oxolane + ethyl 1,1-dimethylethyl ether and Oxolane + 2-propanol exhibit slight to moderate positive deviations from ideal behavior and no azeotrope is present. The system propan-2-one + trichloromethane exhibits negative deviations from ideal behavior and presents an azeotrope. The excess volumes of the system Oxolane + ethyl 1,1-dimethylethyl ether are negative over the whole mole fraction range while those of the system Oxolane + 2-propanol are positive. Excess volumes of the system propan-2-one + trichloromethane, change from negative to positive as the concentration of propan-2-one increases.

polyazeotropic behavior in the binary system 1 1 1 2 3 4 4 5 5 5 decafluoropentane Oxolane
Journal of Chemical & Engineering Data, 2001Co-Authors: Sonia Loras, Jaime Wisniak, Antonio Aucejo, Juan B. Montón, Hugo SeguraAbstract:Vapor−liquid equilibrium data at (26.68, 35, and 55) kPa over the whole concentration range and vapor−liquid equilibria at (23 and 45) kPa over a partial concentration range have been determined for the binary system 1,1,1,2,3,4,4,5,5,5-decafluoropentane (HFC-4310mee) + Oxolane (THF), in the temperature range (294 to 322) K. Pure component vapor pressures of each constituent have also been measured in the range of boiling temperatures of the mixture. Depending on the concentration range, the system exhibits positive and negative deviations from ideal behavior. Two azeotropes, rich in Oxolane and with opposite deviations, have been found both at (23, 26.68, and 35) kPa, while no azeotrope appears at (45 and 55) kPa. According to these results, polyazeotropic behavior ends in a tangent azeotrope as the pressure increases. The vapor−liquid equilibrium data of the solutions were correlated with the mole fraction by the Redlich−Kister equation.

excess molar enthalpies of binary mixtures containing poly ethylene glycol 200 four cyclic ethers at 288 15 298 15 and 313 15 k and at atmospheric pressure
Thermochimica Acta, 2003Co-Authors: Stefano Ottani, Romolo Francesconi, Fabio Comelli, Carlo CastellariAbstract:Abstract Excess molar enthalpies, H m E , of binary mixtures containing poly(ethylene glycol) (PEG) 200+1,3-diOxolane, PEG 200+1,4-dioxane, PEG 200+Oxolane and PEG 200+oxane were determined using a flow microcalorimeter at (288.15, 298.15 and 313.15) K and at atmospheric pressure. The H m E curves are always positive, with maxima varying from 393 J mol −1 (1,3-diOxolane) to 658 J mol −1 (Oxolane), showing asymmetrical trends. The effect of the temperature is well marked on the calorimetric data that increase as the temperature is increased. The Redlich–Kister polynomial was used to estimate the binary fitting parameters. Root-mean-square deviations from the regression lines are reported.
