    Thermodynamic properties of metastable liquefied inert gases: Part 2. P, T-properties of superheated krypton [Electronic resource] / V. G. Baidakov, T. A. Gurina // Physica B: Condenced Matter. - 1989. - Vol.160, №2. - С. 221-230

KRYPTON -- INERT GASES -- THERMODYNAMIC PROPERTIES
Аннотация: The paper presents the results of investigations of the P, ϱ, T-properties of krypton in stable and metastable phase states. Experimental data have been obtained in a temperature range from 150 to 200 K and pressure range from 5.3 MPa to pressures close to the boundary of spontaneous boiling of superheated liquids. The method of pycnometry was used to measure orthobaric densities (116–160 K). The problem of the equation of state and stability boundary of metastable systems is discussed. An equation of state for the superheated liquid has been obtained in the framework of the mean-field theory and thermodynamic perturbation theory. The spinodal has been approximated

EQUATION OF STATE -- PRESSURES -- MPA
Аннотация: A procedure for constructing the equation of state for metastable and labile regions in the liquid gas phase transition is suggested. A consistent description of p, rho, T, and caloric properties was obtained. The spinodals of both pure fluids and their mixtures were located

HOMOGENEOUS NUCLEATION -- OXYGEN -- KRYPTON
Аннотация: The nucleation of the vapor phase in superheated nitrogen-helium liquid solutions was studied by lifetime measurements. The temperature dependences of the mean lifetime of metastable solutions were obtained at p = 0.5 and 1.0 MPa and several concentrations. The nucleation rate J was found to vary from 10(4) to 10(8) s(-1) m(-3). The adsorption of the high-volatility component on the metastable liquid-critical bubble boundary was shown to play a determining role in decreasing the temperature of the attainable solution super-heating as the solution concentration increased. The experimental data were compared with homogeneous nucleation theory. Systematic discrepancies were obtained; these discrepancies were related to the influence of the size effect on the surface tension of a nucleus and the work of its formation

PHASE SEPARATION -- CRITICAL SOLUTION
Аннотация: The (T, p, x) surface of (liquid + liquid) phase equilibrium has been investigated in the vicinity of the line of lower critical solution points of [(1 - x)H2O + x (CH3)CH3(CH2)42PO]. Measurements were carried out in a high-pressure optical chamber at pressures p in the range from 0.1 MPa to 230 MPa. The behaviour of critical exponents for (p, x) and (T, x) phase-equilibrium diagrams: T and p, respectively, has been studied along the critical line and at the double critical point (DCP) with coordinates PD = 127 MPa and TD = 296.5 K. The exponent p retains its value along the line of critical points, including the double critical point; T increases anomalously with an approach to the DCP????????
