ABSTRACT
Phase equilibrium data for the system tetraethyl orthosilicate (TEOS)-carbon dioxide (CO2) are presented. The measurements were conducted in a variable volume phase monitoring cell at different temperatures (306.2, 313.2, 323.2, 333.2, and 343.2) K. The mole fraction of TEOS in the binary mixture was varied from 0.00 to 0.08. The data were fitted using the Peng-Robinson equation of state. The model accounts for literature data on phase behavior over the entire composition range.
