Vapor Pressure Measurements

Molar excess free energies of the systems dimethylsulfoxide–water and propylene carbonate–water have been calculated from static vapor pressure measurements at 25 °C. Enthalpies of mixing at low water concentrations have also been determined. Possible association interactions in these systems are discussed.

Molar excess free energies of the systems sulfolane-benzene and sulfolane–dichloromethane have been calculated from static vapor pressure measurements at 30.00 °C. Refractive indices, excess partial molar volumes of mixing, and enthalpies of mixing at infinite dilution of benzene and dichloromethane were also determined.

Heats Of Vaporization

Abstract A polemic is given regarding the calculated thermodynamic quantities reported in the published paper by Farschi and coworkers. The graph used to calculate the molar heat of sorption of organic probe molecules onto the liquid DL-limonene stationary phase erroneously plots the reciprocal of the centigrade temperatures, rather than the reciprocal of the Kelvin temperatures. Molar heats of vaporization of the organic probe molecules reported in the paper are abnormally small and are not in accord with published values determined from calorimetric and vapor pressure measurements.

Eutectic Melt

The reaction between gaseous titanium tetrachloride and the eutectic melt of potassium and lithium chlorides was investigated at various temperatures and pressures. It was found that, at an optimum temperature of 370 °C, titanium tetrachloride vapor at a pressure of 1 atm reacts with the potassium chloride in the eutectic to yield K2TiCl6 as a solid mixture with lithium chloride.The solubilities of K2TiCl6, and the partial molar properties of the solutions of K2TiCl6, and of potassium chloride, in the eutectic melt of potassium and lithium chlorides were obtained by vapor pressure measurements. It was found that the solubility of titanium tetrachloride increases from 1.5 weight% at 420 °C to 5 weight% at 500 °C. The activities of K2TiCl6, and of potassium chloride, indicate positive deviations from ideality.
