Methods for the approximate calculation of critical parameters of mole
cular inorganic compounds from a single experimental characteristic of
a compound under study, its boiling point, have been given. It was sh
own that a reasonably precise forecast of critical parameters for nonp
olar and weakly polar compounds is possible in the complete absence of
experimental parameters of the compound under study. The critical par
ameters of a series of poorly studied inorganic compounds were determi
ned using the outlined methods.
