Melting of rare gas solids Ar, Kr, Xe at high pressures and fixed points in the P - T plane

Based on the first principles and quantum mechanics, a new approach is put forward to calculate the cohesive energy of face-centered cubic solid neon, in which both the two-body and the total many-body interaction potentials are reasonably emphasized by a new combination formula. It shows that the new scheme is a simple and accurate tool to understand the high-pressure behaviors of solid neon, and it will be applied to calculate the compression curves of dense Helium, Argon, Krypton and Xenon at very high pressures. It is expected that this method can be applicable to all rare gas, including the gas, solid, and liquid phase regions, even of molecular systems, ionic systems.

Absolute and Gibbs excess sorption isotherms of Kr and Xe have been measured at a range of temperatures between 0 and 450 °C and at high pressures in zeolites X and Y (near-faujasites); zeolite A; H-Zeolon and Na-Zeolon (near mordenites); chabazite; and an active carbon, to compare their efficiencies in reducing the rare gas pressures in high-temperature, high-pressure systems. At 450 °C the best sorbents for the purpose were chabazite and the carbon. The isotherms have been analysed to give distribution equilibrium constants for absolute sorption and associated standard thermodynamic quantities (Δ A ⊖ , Δ E ⊖ and Δ S ⊖ ). Isosteric heats have been derived and compared as functions of amount sorbed both for absolute and for Gibbs excess uptakes. These heats differ substantially for larger uptakes, but converge as the uptake decreases. Differential entropies of the intracrystalline rare gas have been calculated for absolute sorption. They decline monotonically with amount sorbed and have temperature coefficients which appear not very different from values expected for classical oscillators.
