ABSTRACT
The phase behavior of methnol triolein systemwas determined experimentally at 6.0, 8.0 and 10.0MPa in the temperature range of 353.2 463.2 K. The results demonstrated that the miscibility of the system was rather poor at low temperature, and the miscibility could be improved by increasing temperature. At a higher pressure, the miscibility was more sensitive to temperature as pressure was fixed. The critical temperature, critical pressure, and acentric factor of triolein were estimated and the experimental data were correlated using the Peng Robinson equation of state. The calculated data agreed reasonably with the experimental results.
