Binary vapor liquid equilibrium p T x data were measured for R22 +DMF (N,N-dimethylformamide) system at temperature from 283.15 to 363.15K by the circulating method. The experimental data are correlated by the Peng Robinson Stryjek Vera equation of state using the Wong Sandler mixing rule with NRTL model. The overall deviation of the pressure is 0.57%. The results reveal that the correlated data have a good agreement with the experimental ones. It is shown that the mixture has a large negative deviation from Raoult s law. The vapor liquid equilibrium characteristics of the mixture are expressed in a log p-1/T diagram and pressure composition diagram for use in the analysis of an absorption refrigeration system.
