The present work reports valuable experimental high-pressure density data for dimethyl carbonate, diethyl carbonate, n-octane, n-decane pure components and their binary mixtures dialkyl carbonate + n-alkane at temperatures between 288.15 K - 308.15 K and pressures between 0.1 MPa - 40 MPa. The experimental density values were compared with experimental information available in the literature. While the volumetric properties for dimethyl carbonate + n-alkane were reported in many works, the diethyl carbonate + n-alkane were less studied. The purpose of this study is to extend the available experimental information about the thermophysical behavior of this kind of mixtures, which is useful in the fuel field. The experimental density data were correlated using a modified Tait equation and were predicted by Nitta-Chao group contribution model.
