Abstract


In the present study, surface light scattering (SLS) was used for the simultaneous determination of liquid kinematic viscosity and surface tension of 2,3,3,3-tetrafluoroprop-1-ene (R1234yf and of trans-1,3,3,3-tetrafluoroprop-1-ene (R1234ze) under saturation conditions. A new SLS apparatus was built up and checked with 1,1,1,2-tetrafluoroethane (R134a), and a good agreement of our data from SLS with literature could be found. With the new apparatus, R1234yf and R1234ze were investigated in the temperature ranges between (293 and 365) K and between (295 and 373) K. For determination of the liquid kinematic viscosity the expanded uncertainties on a confidence level of more than 95 % (k = 2) are estimated to be +/- 2 % for reduced temperatures T-r (= T/T-c) < 0.95, and +/- 6 % for T-r close to 0.99. For the surface tension, the expanded uncertainties are less than +/- 1.5 % (k = 2) in the whole temperature range.
