Abstract
Experimental studies of high-temperature phase equilibria in the BaCl2-NaCl-H2O made it possible to determine the conditions of heterogenization of homogeneous supercritical (SC) fluids spreading from the BaCl2-H2O binary subsystem of type 2 and to reveal the continuity of the transformation of gasliquid equilibria into equilibria of phase separation in SC environment. Comparison with the characteristics of the K2SO4-KCl-H2O system suggests that ternary systems with one volatile component formed by binary subsystems of type 2 with phase separation and of type 1 without separation have the same type of phase diagrams.
