Compressed Liquid Densities and Excess Volumes of CO₂ + Decane Mixtures from (313 to 363) K and Pressures up to 25 MPa

Abstract

Experimental liquid densities of decane and of CO2 (1) + decane (2) binary mixtures (at five different compositions, x1 = 0.0551, 0.2369, 0.4536, 0.8114, and 0.9663) were measured from (313 to 363) K and at pressures up to 25 MPa. The densities of decane were fitted to the Benedict−Webb−Rubin−Starling equation of state (BWRS EoS). Excess molar volumes are calculated by using decane densities calculated from the BWRS EoS and CO2 densities calculated from the Span−Wagner EoS.
