Dielectric and volumetric properties of supercritical carbon dioxide(1) + methanol(2) mixtures at 323.15 K

The static dielectric constant and density of carbon dioxide-methanol mixtures were measured at 323.15 K as a function of pressure in the range 10-18 MPa, and methanol mole fraction up to 0.16. The results, along with those obtained by other authors, allow a complete description of the dielectric an...
