SulfurDioxide
SulfurDioxide provides high accuracy thermodynamic properties for sulfur dioxide (SO2, MW 64.06 g/gmole, CAS No 7446-09-5) using the Fundamental Equation of State presented by:
Kehui Gao and Jiangtao Wu
"A Helmholtz Energy Equation of State for Sulfur Dioxide"
J. Chem. Eng. Data 2016, 61, 2859-2872
The correlation is valid for temperatures in the range between triple point at 197.7 K to 525 K for pressures less than 35 MPa. Enthalpy and entropy values are referenced to 0 for saturated liquid at at the normal boiling point (263.137 K);
(Versions previous to 2.013 used the equation of state by Eric W. Lemmon, Roland Span, "Short Fundamental Equations of State for 20 Industrial Fluids", J. Chem. Eng. Data, 2006, 51 (3), 785-850)
