[en] Works devoted to the development of calculation methods in the Laboratory of Chemical Thermodynamics at the Chemistry Department of Moscow State University are briefly reviewed. The main stages of this activity are described. The names of the scientists who contributed most to the development of these studies are given, along with the most valuable results of the last 60 years.

[en] Vapor pressure was determined by static method at 298.15 K, and the solvent activity values were calculated for the Zn(CH3SO3)2–H2O and Cu(CH3SO3)2–H2O systems. Parameters of the Pitzer–Simonson–Clegg model were obtained from data on the vapor–liquid (VLE) and solid–liquid (SLE) equilibria. Stability parameters of hydrates Zn(CH3SO3)2 · 12H2O, Zn(CH3SO3)2 · 4H2O and Cu(CH3SO3)2 · 4H2O were estimated. Phase diagram fragments were calculated.
