Calculation of vapour-liquid equilibria from vapour pressure data
Chemical Engineering Science, 1962Abstract The application of rigorous thermodynamic methods allows the calculation of vapour-liquid equilibrium data for binary systems from measurements of the total vapour pressures exerted by the liquid phase. Of the methods known, integration of the coexistence equation is considered most convenient.

Metal Vapour in Atmospheric-Pressure Arcs
IEEJ Transactions on Power and Energy, 2010Metal vapour has a significant, and in some cases dominant, influence in many applications of atmospheric-pressure plasmas, including arc welding, circuit interruption and mineral processing. While the influence of metal vapour has long been recognized, it is only recently that diagnostic and computational tools have been sufficiently well-developed to

Vapour pressure of selenium trioxide
Recueil des Travaux Chimiques des Pays-Bas, 1964AbstractThe vapour pressure of solid and liquid SeO3 was measured in the temperature range between 80°C and 120°C. Measurements are easily affected by the presence of residual SO3. The triple point is situated at 120.9°C and 5.5 mm Hg. The plot of log p against 1/T shows that the heat of vaporisation depends greatly on temperature. Sublimation pressure

Reference values of vapour pressure the vapour pressures of benzene and hexafluorobenzene
The Journal of Chemical Thermodynamics, 1981Abstract The vapour pressures of benzene and hexafluorobenzene in the range 10 to 100 kPa were measured in the course of developing a comparative ebulliometric apparatus, and the results of four sets of measurements on benzene and of one on hexafluorobenzene are given.

The vapour pressure of tetrafluoromethane
Cryogenics, 1979Abstract The vapour pressure of tetrafluoromethane has been measured at its triple-point temperature (89.56 K), and at six higher temperatures up to 173 K. These temperatures were those of the triple-points of six pure substances which had previously been carefully determined and which have been corrected to IPTS-68.

Vapour pressure of some phthalocyanines
Journal of Porphyrins and Phthalocyanines, 2000Mass spectrometric studies of the composition of the gaseous phase under solid compounds of free phthalocyanine ( H 2 Pc ) and its complexes with aluminium ( AlClPc , AlFPc , ( AlPc )2 O ) and copper ( CuPc ) were performed in the temperature range up to 700 °C.

Vapour Pressure of Potassium Amalgams
Nature, 1934IF a solution of a substance has a smaller surface tension than the pure solvent, the solute is adsorbed or concentrated at the surface, in accordance with Gibbs's theorem. It is therefore to be expected that the vapour pressure of the solvent of such a solution will be higher, when the concentration of the solute is made the same in the surface as in ...
