The Size Effect for Liquid–Liquid Phase Equilibrium in a Ternary System

Abstract

Size effects during phase transformations in submicrometer- and nanometer-sized systems manifest themselves in a substantial change of the phase diagrams. The construction of phase diagrams of small-volume ternary and multicomponent systems has not yet been mastered. Using an aniline–methylcyclopentane–hexane solution as an example, the effect of the particle (droplet) size on the region of segregation of droplets with a core–shell configuration with a radius of 100 and 50 nm at temperatures of 25 and 45°C is simulated by the methods of chemical thermodynamics. For this system, a decrease in the volume leads to a change in the region of heterogeneity, to the appearance of metastable states that are absent in macrophases, and to an increase in the thermodynamic stability of a homogeneous solution of poorly soluble components.
