1.
The thermodynamic theory of the separation of mixtures of substances in cascades has been extended to the region of partition chromatography with the use of the concept of an ideal fine-separation cascade. On the basis of an analysis.of the change in the entropy of mixing in a process taking place in astep of a cascade, we have obtained an equation which defines the specific work of separation of a single step and the separating power of the cascade as a whole. This equation is distinguished from the known equation by the factor RT/2.

2.
The relationship between the general theory of separation in cascades and the theory of partition chromatography has been established and substantiated. It has been shown that the specific work of separation of a step of an ideal fine-separation Chromatographic cascade includes the work for the transfer of one mole of each of the substances being separated through the phase boundary.
