摘要：

Measurements of D-pinitol solubility in supercritical CO2 in the temperature range (313 to 333) K and pressures ranging from 10 to 40 MPa are reported for the first time in this work. Two different thermodynamic models are applied to correlate the experimental D-pinitol solubilities: a cubic-type equation of state (the Soave-Redlich-Kong, SRK) and a model based on the group contribution approach (the Group Contribution Equation of State, GC-EoS). Both models demonstrate high capability to describe the solid-gas-phase equilibria of this system. In addition, values for the thermophysical properties, sublimation pressure, and solid molar volume of D-pinitol are also given.
