摘要：

Solubilities of 1-hexanol, or 1,2-hexanediol, or 2-hydroxypropanoic acid ethyl ester, or 2-hydroxyhexanoic acid ethyl ester in supercritical CO2 have been measured at T=(311, 318, and 323, or 328)K in the pressure range from 1 MPa to 8 MPa. The measurements have been performed using a flow-type equipment coupled with a novel analytical procedure. An accurate correlation method for the solubility of low volatile substances in supercritical CO2 based on the equilibrium condition for the solute has I,een proposed and successfully applied for the interpolation of our experimental results.
