摘要：

The temperature dependency of the saturated vapor pressure of Ir(acac)(3) has been measured by the method of calibrated volume (MCV), the Knudsen method, the flow transpiration method, and the membrane method. The thermodynamic parameters of phase transition of a crystal to gas were calculated using each of these methods, and the following values of Delta H-T(0) (kJ mol(-1)) and Delta S-T(0) (J mol(-1) K-1), respectively, were obtained: MCV: 101.59, 156.70; Knudsen: 130.54, 224.40; Flow transpiration: 129.34, 212.23; Membrane: 95.45, 149.44 Coprocessing of obtaining data (MCV, flow transportation method and Knudsen method) at temperature ranges 110-200 degrees C as also conducted:Delta H-T(0) =127.9-2.1 (kJ mol(-1)); Delta S-T(0)=215.2-5.0 (J mol(-1) K-1).
