ABSTRACT
Densities in the liquid phase were measured for (1,1,1,2-tetrafluoroethane + triethylene glycol dimethyl ether) using a vibrating-tube densimeter. Three mixtures with a molar fraction of refrigerant of 0.9485, 0.9655, and 0.9798 have been considered at temperatures from (283 to 323 K) at pressures up to 6 MPa. Such ranges are approximately those of interest for a compression refrigeration plant. The data at each composition were correlated with a Tait equation, and the excess volumes were also provided.
