Ezperimental System for pvT(z) Properties and Vapor Pressure Measurements of 1,1,1,3,3-Pentafluoropropane

摘要：

The vapor pressures of 1,1,1,3,3-pentafluoropropane (HFC-245fa) were measured using the new pvT(x)property measurements system from (236 to 427) K. The experimental system includes the Burnett-Isochoric apparutus,the temperature measurement system, the thermostatic bath, the pressure measurement system and the vacuum system. The uncertainty of the vapor pressure was estimated to be ± 100Pa. The vapor pressure results were also compared with the available literature data.
