HFO1336mzz(Z) provides approximate thermodynamic property data for cis-1,1,1,4,4,4-Hexafluoro-2-butene, MW 164.056 g/gmole, CAS# 692-49-9).  This fluid is also known DR-2 and Formacel«1100.  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 data provided by:

The properties are valid for temperatures between 270 K and 500 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 the liquid phase are estimated for temperatures between 270 K and 430 K based using a corresponding states approach as suggested in:
