The isobaric specific heat capacity and viscosity for 3,3,3-trifluoroprop-1-ene in liquid phase at temperatures from (230 to 293) K and pressures up to 8 MPa

Abstract

In this paper, the 65 isobaric specific heat capacity (cp) and 9 viscosity (η) data of 3,3,3-trifluoroprop-1-ene (R1243zf) were measured at temperatures from (230 to 293) K and pressure up to 8 MPa using a flow calorimeter and a vibrating-wire viscometer. The uncertainty of temperature, pressure, isobaric specific heat capacity and viscosity were evaluated to be less than 11 mK, 0.02 MPa, 1.0 % and 2.7 %, respectively. Three saturated liquid viscosity (ηs) data were obtained based on the extrapolation of the viscosity data. Empirical correlations were established based on the cp and ηs data, the average absolute relative deviation for cp and ηs are 0.5 % and 1.3 %, respectively.
