Abstract
Both vapor pressures and vapor−liquid equilibria (VLE) of the 2,2,2-trifluoroethanol (TFE) + quinoline system, which can be considered as a potential candidate to overcome serious disadvantages of the existing working fluids used for absorption chillers, were measured in order to determine the allowable operation range of this organic mixture. Vapor pressures were measured by using the boiling point method in the temperature range of 293.15 K to 458.55 K and in the concentration range of (0.0 to 100.0) mass percent of TFE and were correlated with an Antoine-type equation. The resulting average absolute deviation (AAD) between the experimental and calculated values was found to be 2.22%. The isobaric VLE data of the 2,2,2-trifluoroethanol (TFE) + quinoline mixture were measured at three different pressures of (13.33, 53.33, and 101.33 kPa), and the thermodynamic consistency was checked by using the point test method.
