R1336mzz(Z) (also referred to as HFO1336mzz(Z)) provides property data for cis-1,1,1,4,4,4-Hexafluoro-2-butene, MW 164.06 g/gmole, CAS# 692-49-9).  This fluid is also known DR-2 and Formacel®1100.  The thermodynamic properties are obtained using the reduced Helmholtz equation of state determined by McLinden, M.O. and Akasaka, R., as it ius provided in the REFPROP 10 program.


The properties are valid for temperatures between 182 K and 500 K for pressures up to 46 MPa.


The IIR reference is used for specific 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 200 K and 500 K for gaseous states and between 185 K and 444 K for liquid states.based using a corresponding states approach as suggested in:
