Compressed liquid densities for DMF and for CO2 (1) + DMF (2) binary mixtures are reported from (313 to 363) K and up to 25 MPa. Densities were measured for binary mixtures at nine different compositions, x1) 0.2618, 0.2876, 0.4068, 0.4268, 0.4461, 0.4502, 0.6235, 0.8091, and 0.9311. There are no experimental density data concerning CO2 + DMF mixtures reported in the literature. The estimated uncertainty is (0.20 kgam-3 for the experimental compressed liquid densities. Densities of DMF were correlated with the Benedict-Webb-Rubin-Starling equation of state (BWRS EoS) and the Tait equation. A fiveparameter equation was used to correlate the experimental densities of DMF and CO2 + DMF mixtures. Excess molar volumes were determined using DMF densities calculated from the BWRS EoS and CO2 densities calculated from the Span-Wagner EoS.
