Abstract:
Using the methods of equilibrium chemical thermodynamics, the influence of the size and initial composition of stratifying organic mixtures in microsized pores on the composition and stability of phases coexisting in a heterogeneous state has been demonstrated. Using a number of binary organic systems as an example, it is shown that, in contrast to macrosized phases, in microsized pores, the mutual solubility of the components substantially depends on the pore size and the initial composition of the mixture, while the nature of the size dependence of solubilities is different for mixtures of different compositions. A thermodynamic interpretation of the results obtained as a consequence of the implementation of various mechanisms to reduce the free energy of the system is presented.
