Distribution of solutes between coexisting steam and water

Distribution ofB(OH)3between water and steam at high temperatures

“…However, model calculations have convinced us that the temperature dependence of J , which is characteristic of the second virial coefficients, is greatly reduced at densities above the critical density of water ρ c1 , so in equation (5) we have multiplied the exponential term by 4 . In order to incorporate the information about B(OH) 3 distribution between water and steam reported here, the expression obtained by integration of equation (5) was used to calculate the set of experimental T ln K D which was also subjected to the fitting procedure.…”

“…(3,4) We determined the concentration of solutes in the solutions which were in equilibrium either with the gaseous or with the solid solutes. These studies provided valuable information about the thermodynamics of dilute solutions in near-critical solvents.…”

Solubility in fluids close to their critical points

“…In all the cases where it was possible, relationship (15) was verified within the experimental uncertainty of the involved quantities. The linear asymptotic range covered by eq (14) extends around 150 K from Tcl for the systems studied in ref( [15]). This extended linear behaviour is due [9] to the great difference in volatility of the two components forming the binary system.…”

Properties of Mixtures with Water

“…They are listed for some important electrolytes in the following: where r w is the density of pure water (g cm À3 ). Near the critical temperature of water, a more theoretical-based expression may be preferred that relates the slope of the pressure to the mole fraction in the liquid phase [87]:…”
