Solubility of trans-1,3,3,3-tetrafluoroprop-1-ene (R1234ze(E)) in pentaerythritol tetrapentanoate (PEC5) in the temperature range from 283.15 to 353.15 K

• The solubilities of R1234ze(E) in PEC5 have been measured based on the isochoric method.
• The data were correlated using the PR EoS with Huron–Vidal mixing rules and NRTL equation.
• The Henry's constant of R1234ze(E) in PEC5 at different temperatures was obtained.

The solubilities of trans-1,3,3,3-tetrafluoroprop-1-ene (R1234ze(E)) in pentaerythritol tetrapentanoate (PEC5) have been measured from 283.15 to 353.15 K based on the isochoric method. The experimental solubility data were correlated using the Peng–Robinson equation of state with Huron–Vidal mixing rules and the NRTL equation for the excess Gibbs energy at infinite pressure. The absolute average deviation between experimental data and calculated values was 0.92%, and the maximum relative deviation was 3.94%.
