**ETHANOL**

ETHANOL provides high accuracy thermodynamic properties for deuterium (Molar mass =46.069 kg/kmol) using the Fundamental Equation of State, as described by:

J. A. Schroeder, S. G. Penoncello, and J. S. Schroeder

"A Fundamental Equation of State for Ethanol"

Journal of Physical and Chemical Reference Data 43, 043102 (2014)

This implementation in version 9.755 replaces the previous less accurate equation of state described in the following paper:

H.E. Dillion and S.G. Penoncello

"A FUNDAMENTAL EQUATION FOR THE CALCULATION OF THE THERMODYNAMIC PROPERTIES OF ETHANOL"

Fifteenth Symposium on Thermophysical Properties, June 22-27, 2003, Boulder, Colorado, U.S.A.

Note that the reference state in the current implmentation differs from the reference state that was used in this earlier implementation..

**Reference State **

** ** h =200 kJ/kg, s = 1.00 kJ/kg-K at 273.15 K, saturated liquid. The reference state can be changed using the $Reference directive.

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

160 K < T < 650 K

0 < P < 280 MPa

__Correlations for viscosity and thermal conductivity of ethanol were obtained from:__
