The densities, surface tensions, and viscosities were measured at 301.15 K for the blends of {diesel plus diethyl apidate (DEA)}, {diesel plus diethyl carbonate (DEC)}, {diesel plus diglyme (DGM)}, {diesel plus dimethyl carbonate (DMC)}, and {diesel plus dimethoxymethane (DMM)}. On the basis of the experimental data, the excess thermodynamic properties, including excess densities, excess surface tensions, and excess viscosities, were determined as functions of mass fractions over the entire composition range. Furthermore, polynomial correlations were fitted for the excess thermodynamic properties.
