ABSTRACT
The solubilities of trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) in pentaerythritol ester heptanoic acid (PEC7) and in pentaerythritol tetranonanoate (PEC9) have been measured based on the isochoric method at temperatures ranging from 283.15 to 353.15 K. The experimental solubility data were correlated by Peng Robinson equation of state with HVOS mixing rule in which the excess Gibbs energy at infinite pressurewas represented by WILSON equation. The absolute average deviation and maximum deviation of the pressure from the calculated values was 0.97% and 3.84% for R1234ze(E) + PEC7 system, respectively. For R1234ze(E) + PEC9 system, the absolute average deviation and maximum deviation of pressurewas 0.93% and 3.95%, respectively. The results showed a good agreement with the experimental data.
