n-UNDECANE provides high accuracy thermodynamic properties for n-undecane (Molar mass = 156.31 g/mole) using the Fundamental Equation of State presented in


Aleksandrov, I. S.; Gerasimov, A. A.; Grigor'ev, B. A., 2011,

Using Fundamental Equations of State for Calculating the Thermodynamic Properties of Normal Undecane,

Thermal Engineering, 58:691-698.  


Note that there is an error in Eqn 7 of this paper.  The exponents for tau on the first three terms should be 1.5, 0.25, and 1.25, respectively.  (Thanks to Eric Lemmon at NIST and Ian Bell ( for help in identifying this error.)


Reference State 

    h = 0 kJ/kg, s = 0 kJ/kg-K at 0 K for the equilibrium molecular crystal

    The reference state can be changed using the $Reference directive.


Range of applicability for equation of state:

   247.6K < T < 650 K

 density/critical density >= 2


Transport properties are provided using correlations given in:
