Key words: propylene glycol, supercritical propane / butane mixture, phase equilibrium, solubility, Peng—Robinson equation of state, Mukhopadhyay and Rao mixing law
The phase equilibrium of the propylene glycol—propane/butane system and the solubility
of propylene glycol in supercritical propane-butane mixture at temperatures 403, 423
and 443 K using a high-pressure optical cell were studied. The results were described
using the Peng—Robinson equation of state and the Mukhopadhyay and Rao mixing
law.
