Abstract

The vapor-liquid equilibrium of binary mixtures of xenon + S[F.sub.6] was measured at nine temperatures from 235.34 to 295.79 K and pressure up to 6.5 MPa. The mixture critical line is continuous between the critical points of the pure components, hence the system is classified as type 1 phase behavior in the scheme of van Konynenburg and Scott.

2. A molecular dynamics study of the thermodynamic properties of calcium apatites. 1. Hexagonal phases

Subjects

Abstract

Structural and thermodynamic properties of crystal hexagonal calcium apatities were investigated using an all-atom Born-Huggins-Mayer potential by a molecular dynamics technique. The accuracy of the model at room temperature and atmospheric pressure was checked against crystal structural data, with maximum deviations of ca. 4% for the haloapatites and 8% for hydroxyapatite.

Abstract

A study of the thermodynamic functions of the liquid mixtures xenon + n-butane and xenon + isobutane is presented. It is shown that the mixtures have a similar behavior to that of other xenon + alkane mixtures.

Abstract

Measurements of total vapor pressures for liquid mixtures of xenon + propane at 161.40, 182.34 and 195.49 K and of xenone + ethane at 161.40 and 182.34 K reveal negative deviations from Raoult's law at all temperatures. The thermodynamics of the two liquid mixtures are further discussed.

Abstract

A new apparatus, based on the static and analytical method, is developed for the study of vapor-liquid or vapor-liquid-liquid equilibrium. The equilibrium vapor pressures of (xenon + methane) binary mixtures are measured and the results have been correlated by the Peng-Robinson equation of state.

33. Liquid–vapour equilibrium of {xBF3 + (1 − x)n-butane} at 195.49 K

*SATURATION vapor pressure, *XENON
Abstract

The saturation vapour pressure of {x BF3 + (1−x)n-C4H10} has been measured at 195.49 K. The system shows large positive deviations from Raoult’s law and liquid–liquid immiscibility over a wide composition range whose limits have been estimated as 0.39±0.030.9785. The excess molar Gibbs energies (GmE) have been calculated as a function of composition from the vapour pressure data. For the hypothetical equimolar mixture GmE (x=0.5) = (703.9±29) J mol−1. The results were interpreted using the statistical associating fluid theory for potentials of variable range (SAFT-VR), as well as compared with those of related systems, such as (BF3 + n-pentane) and (BF3 + xenon).
