AbstractThe relative permittivities (∈r) of dimethyl ether (DME) + carbon dioxide (CO2) mixtures [(0.25, 0.48, and 0.75) mass fraction of DME] were measured at (313 and 333) K in the pressure range (3.9 to 32.5) MPa. The Peng-Robinson equation of state was used to calculate the mixture compressed liquid densities (ρcalcd), and the relative permittivity was fitted to ρcalcd, the temperature (T), and the mass fraction of DME (φ1) using a simple empirical equation. © 2008 American Chemical Society.
