ABSTRACT
The surface tension and liquid viscosity of two binary refrigerant mixtures 1,1,1,2-tetrafluoroethane (R32) (1) + 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) (2) and R32 (1) + trans-1,3,3,3-tetrafluoroprop-1-ene (R1234ze) (2) have been measured from 293 K to the critical point by using the surface light scattering (SLS) method. The experimental data were correlated as a function of temperature and mole fraction of the pure components. For the surface tension of R32+R1234yf and R32+R1234ze, the average absolute deviations are 0.053 and 0.029 mN*m 1, respectively. As for the liquid viscosity, the relative percentage average absolute deviations are 0.86 and 1.01%, respectively.
