BENZENE provides high accuracy thermodynamic properties for benzene (Molar mass = 78.112 g/mole) using the Fundamental Equation of State presented in


Thol, M., Lemmon, E.W., Span, R.

"Equation of state for benzene for temperatures from the melting line up to 750 K and pressures up to 500 MPa,"

provided as an extra edition for the 9th ATPC in Peking 2010, published by High Temperature - High Pressure

Reference State 

    h = 0 kJ/kg, s = 0 kJ/kg-K for ideal gas properties at the normal boiling point of 353.21635 K.  

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


Range of applicability for equation of state:

     278.674 K < T < 750 K

     0 < P < 500 MPa


Transport properties are provided using correlations given in:
