Abstract Article is devoted to the extension of the known rules of thermodynamics of heterogeneous systems (on changes of temperature at constant pressure, pressure at constant temperature, chemical potential of the solvent at constant temperature and pressure) to systems with an arbitrary number of components and phases, as well as phase equilibrium of various types: liquid-vapor, solid-vapor, fusibility diagrams, solubility diagrams (including delamination in condensed phases). Generalized analogs of Gibbs–Konovalov laws, Vrevskiy laws, Gibbs–Roozeboom rules, Schreinemakers rules, Van Rijn rule, Gibbs rule are formulated. Consideration was provided with the help of the concept of heterogeneous phases complex.
