The phase diagram of the system «CO2 — diethylene glycol monoethyl ether (ethylcarbitol)»
was studied on isotherms 308, 318 and 323 K. The available literature data are
supplemented by the results of this study. The obtained data are described using the
Peng—Robinson equation of state and the Mukhopadhyaya and Rao mixing law. A
range of thermodynamic parameters is proposed to effectively remove ethylcarbitol
from polymers during their plasticization and to preserve the components of the
finished product soluble in supercritical CO2.
