DIMETHYLETHER provides high accuracy thermodynamic properties for dimethylether (also called methyoxymethane, methylether, CAS# 115-10-6) (Molar mass = 46.068 g/mole) using the Fundamental Equation of State presented in paper by


Wu, J., Zhou, Y., and Lemmon, E.W.,

"An equation of state for the thermodynamic properties of dimethyl ether,"

J. Phys. Chem. Ref. Data 40, 023104 (2011) 




Reference State 

    h = 0 kJ/kg, s = 0 kJ/kg-K for saturated liquid at the normal boiling point.  The reference state can be changed using the $Reference directive.


Range of applicability for equation of state:

   131.65 K < T < 525 K

0 < P < 40 MPa
