Thermodynamlcs properties of HCFC133a were studied by using experimental method by means of opalescence intensity method, critical temperature and critical density of HCFC133a were measured. By means of constant volume method, saturated density of liquid and vapour,saturated vapour pressure were measured. Furthermore, critical pressure and critical index were determined according to experimental data, and vapour pressure equation with high accuracy was presented.
