R365mfc provides high accuracy thermodynamic properties for 1,1,1,3,3-pentafluorobutane(C5H5F5,  MW 148.07 g/gmole, CAS No.406-58-6) using the Fundamental Equation of State developed by:


Lemmon, E.W, and Span, R. "Thermodynamic Properties of R.227ea, R.365mfc, R.115, and R-13I1",

J. Chem. Eng. Data 2015, 60, 3745-3758


The correlation is valid for temperatures in the range between 239 K to 500 K for pressures less than 35 MPa.  


Enthalpy and entropy values are referenced to 200 kJ/kg and 1 kJ/kg-K, respectively,  for saturated liquid at 0C. 


Thermal conductivity in the vapor state are correlated from data provided in:
