D4 provides high accuracy thermodynamic properties for octamethylcyclotetrasiloxane (C8H24O4Si4, MW=296.616 g/gmole, CAS#=556-67-2) using the Fundamental Equation of State presented in:


Colonna, P., Nannan, N.R., Guardone, A., and Lemmon, E.W.,

Multiparameter equations of state for selected siloxanes,

Fluid Phase Equilibria, 244 (2006) 193-211


The correlation is valid for temperatures in the range between 291 K and  673K for pressures less than 30 MPa.   


Values of specific enthalpy and entropy are referred to 0 for saturated liquid at the normal boiling point (448.5 K).


Transport properties are provided using correlations given in:
