HFE7200 provides approximate thermodynamic property data for hydrofluoroether 7200, MW 250 g/gmole).  This fluid is known by its trade name 3M HFE 7200 NOVEC Engineered Fluid and as  1-ethoxy-1,1, 2,2,3,3,4,4,4-nonafluorobutane and C4F9OC2H5 with CAS number 163702-05-4..  The thermodynamic properties are obtained using the Martin-Hou equation of state (A.I.Ch.E. Journal, 1:142, 1955) as fitted by S.A. Klein, based on corresponding states methods and data reported by:


M.H. Rausch, L. Kretschmer, S. Will, A. Leipertz, and A. Froba

"Density, Surface Tension, and Kinematic Viscosity of Hydrofluoroethers HFE-7000, HFE-7100, HFE-7200, HFE-7300 and HFE-7500"

J. Chem. Eng. Data, 2015, 60, pp. 3759-3765


The properties are valid for temperatures between 270 K and 540 K for pressures up to 10 MPa.


The IIR reference is used for specfic enthalpy and entropy, i.e., h=200 kJ/kg and s=1 kJ/kg-K for saturated liquid at 273.15 K.


Transport properties for liquid HFE7200 and thermal conductivity for the liquid are provided for temperatures between 270 K and 380 K based on information provided by Rausch et al. (2015) and

Thermal conductivity for the vapor phase for temperatures between 270 and 380 K are estimated using a corresponding states approach as described in:
