CH3OH provides ideal gas thermodynamic and transport property data for low pressure gaseous methanol over the temperature range from 200 K to 3500 K.  The ideal gas specific heat is based on data provided by


Bonnie J. McBride, Michael J. Zehe, and Sanford Gordon

"NASA Glenn Coefficients for Calculating Thermodynamic Properties of Individual Species"

The reference state for specific enthalpy is based on the enthalpy of formation relative to the elements (-200,928 at 25 C.  The reference state for specific entropy is based on the Third Law of thermodynamics (239.795 kJ/kgmol-K at 25 C, 101.3 kPa).  These reference state values were obtained from McBride et al. in the above reference.


Transport property information (except for gas-phase viscosity) are also obtained from: Yaws, Carl L., ed. Chemical Properties Handbook. New York: McGraw-Hill, 1999:


Gas-phase viscosity is from:

The low density viscosity correlation is applicable for 240 K< T < 1000 K

The low density thermal conductivity correlation is applicable for 270 K < T < 684 K
