**n-DODECANE**

n-DODECANE provides high accuracy thermodynamic properties for normal dodecane (C12H26, Molar mass =170.33 g/mole) using the Fundamental Equation of State developed by

Lemmon, E.W., Huber, M.L.,

"Thermodynamic Properties of n-dodecane",

*Energy and Fuels*, Vol. 18, No. 4, pp. 960-967, 2004

**Reference State **

** ** h = 0 kJ/kg, s = 0 kJ/kg-K at 298.15 K, 101.325 kPa. The reference state can be changed using the $Reference directive.

**Range of applicability for equation of state**:

263.6 K (triple point) < T < 800 K

0 < P <700 MPa

Thermoconductivity and viscosity data employ the relations presented by:

Huber, M.L, Laesecke, A., and Perkins, R.

"Transport Properties of n-Dodecane"

*Energy and Fuels*, Vol. 18, No. 4, pp. 968-975, 2004.

The transport property correlations are stated to have an uncertainty of <3% for viscosity and <5% for thermal conductivity for pressures up to 200 MPa.

Surface tension data were fit to the functional form proposed by:

G.R. Somayajulu

"A Generalized Equation for Surface Tension from the Triple Point to the Critical Point"

I*nternational Journal of Thermophysics,* Vol. 9, No. 4, 1988

The data used for fitting the surface tension correlation were obtained from the NIST Database 23 (REFPROP 7) program.
