s: The vapor-liquid equilibrium (VLE) data of R1234yf + NMP and R1234yf + DMETrEG were measured at the temperature range of (293.15 ~ 353.15) K in a dual cycle experimental apparatus. The thermodynamic consistency of the VLE data was checked with area test. The VLE data were correlated by NRTL model, and the results showed that they had a good agreement. The average relative deviation of pressure for R1234yf + DMETrEG was within 1.37 % and its maximum was 3.51 %, the average relative deviation of pressure for R1234yf + NMP was within 1.43 % and its maximum was 3.65 %. The results still showed that there was a large positive deviation between the binary system R1234yf + NMP and the Raoul's law, and the system R1234yf + DMETrEG exhibited a slight positive deviation to the ideal solution. Key word: vapor-liquid equilibrium; absorption working pairs; R1234yf; NMP; DMETrEG
