摘要：

A linear approximation of the modified van der Waals-Storonkin equation is obtained, and the properties of the operators appearing in the approximate equation for multiphase multicomponent systems are studied. Generality of the structure of the operators is demonstrated, which is determined by an invariant of a phase-separation region. Distillation-trajectory regions around saddle heteroazeotropes are explored.
