The measurement of excess enthalpies, H-E, at T = 298.15 K and densities at temperatures between 283.15 K and 313.15 K are reported for the (2-methoxyethanol + 1,4-dioxane) and (1,2-dimethoxyethane + benzene) systems. The values of H-E and the excess volumes, V-E, are positive, and the temperature dependence of V-E is quite small for (2-methoxyethanol + 1,4-dioxane). The (1,2-dimethoxyethane + benzene) system shows a negative H-E and sigmoid curves in V-E, which change sign from positive to negative with an increase in 1,2-dimethoxyethane. The temperature dependence of V-E for this system is negative. (C) 2003 Elsevier Ltd. All rights reserved.
