Densitites and excess molar volumes for the eight binary mixtures diethyl carbonate + diethoxymethane, + 1,2-diethoxyethane, + dimethoxymethane, + 1,2-dimethoxyethane, + 1,3-dioxolane, + oxolane, + 1,4-dioxane, or + oxane have been determined at 298.15 K and atmospheric pressure by means of a digital density meter. Excess molar volumes are negative over the entire range of composition for the four mixtures containing Linear ethers and positive in the cases of cyclic ethers with the exception of the diethyl carbonate + 1,3-dioxolane mixture, which presents a sign inversion. The results were correlated by the Redlich-Kister equation.
