Abstract
Two variants of modeling the solubility of palladium hexafluoroacetylacetonate in carbon dioxide (under sub- and supercritical conditions) were considered based on previously obtained experimental data. In the first variant, the Peng–Robinson equation of state was used, and the Chrastil equation was used as an alternative. The optimal parameters of the model equations were found. Both modeling variants made it possible to describe, with satisfactory accuracy, the solubility isotherms in the temperature range of 313–353 K and at mole fractions of the complex up to 0.8%. The standard deviations were 2.6 and 2.0 g/L for the Peng–Robinson and Chrastil equations, respectively.
