Особенности Влияния Исходного Состава Органических Расслаивающихся Смесей В Микроразмерных Порах На Взаимную Растворимость Компонентов

Abstract

The influence of pore size and initial compositions of stratifying organic mixtures in microsized pores on the composition and stability of coexisting phases in a heterogeneous state has been demonstrated by means of equilibrium chemical thermodynamics. Using the example of several binary organic systems, it has been shown that, unlike macrosized phases, mutual solubilities of components in microsized pores substantially depend on the size of a pore and initial composition of a mixture, and even characters of solubility dependences on pore size are different for mixtures of different compositions. A thermodynamic interpretation of the obtained results has also been suggested based on several different mechanisms of lowering the free energy of the system.
