Density data for carbon dioxide (CO2) +trans-1,3,3,3-tetrafluoroprop-1-ene (R-1234ze(E)) mixture at temperatures from 283.32 to 353.02K and pressures up to 10MPa.

Summary

The densities of CO2-R1234ze(E) (trans-1,3,3,3-tetrafluoroprop-1-ene) binary mixture were measured using VTD densitometer, Anton Paar DMA 512, in the gas, liquid and supercritical phases. Four compositions of mixtures: 21.3% CO2+ 78.7% R1234ze(E), 40% CO2+ 60% R1234ze(E), 59.6% CO2+ 40.6% R1234ze(E) and 79.4% CO2+ 20.6% R1234ze(E) were studied at seven temperatures between 283.32 K and 353.02 K and pressures up to 10 MPa. The data were well correlated using the Peng-Robinson cubic equation of State using the Wong Sandler mixing rules involving the NRTL activity coefficient model, and the fundamental Helmholtz equation of state using the Kunz and Wagner mixing rules involving Helmholtz energy. The experimental and correlated phase compositions were compared. Both two models were adjusted on the VLE data, but the Helmholtz model is more accurate to the prediction of density than the Peng-Robinson model.
