Key words: anthracene, supercritical carbon dioxide, the solubility of the specific heat, the thermal effect

In the framework of the development of the catalyst regeneration procedure via supercritical
fluid CO2 extraction, some thermodynamic properties of the «anthracene—
carbon dioxide» mixture in supercritical fluid state are measured. The data on anthracene
solubility in pure and modified (dimethyl sulfoxide, 5 wt. %) supercritical carbon dioxide
(SC-CO2), heat capacity of anthracene and its mixtures with carbon dioxide, as well as
the heat of solution of anthracene in SC CO2 are presented. The anthracene solubility
in SC CO2 is satisfactorily described using the Peng-Robinson equation of state.
