Abstract:
The results of analysis of available experimental data on the pressure dependence of temperature of nonequilibrium boiling of rapidly heated aqueous solutions of hydroperoxide are used to determine the pressure$(P)$–temperature $(T)$–concentration$(x)$ correlation. This correlation is obtained for a solution under conditions of phase equilibrium (saturation surface in three-dimensional space of variables $P$, $T$, and $x$) in a wide range of states, including the critical line. The obtained surface is used to calculate the equilibrium composition of gas over the solution as a function of $x$ and $T$ by solving the Duhem equation.
