New estimation schemes were developed for selected families of binary mixtures (n‑alkane + n‑alkane mixtures, mixtures with CO2, etc.) to obtain estimated interaction parameters for mixtures that have not been fitted.
Abstract
The bubble point pressures of two compositions of each of eight binary mixtures have been measured over a temperature range of 270 K to 380 K. Six of the mixtures included pentane, which was mixed with 1,1,1,3,3-pentafluoropropane (R-245fa); methyl perfluoropropyl ether (R-E347mcc); 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone; 1,1-dichloro-1-fluoroethane (R-141b); trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)); and dimethyl ether. The two remaining binary mixtures were 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone + methyl perfluoropropyl ether (R-E347mcc) and butane + R-245fa. Interaction parameters for a Helmholtz energy mixture model were fitted for each mixture. Bubble point data are reported as well as mixture parameters, along with deviations of the data from their respective nist-equations. These mixtures are of interest as working fluids in organic Rankine power cycles.
