Abstract

The density of the 2-chloroethanol (CE) + 2-methoxyethanol (ME) + 1,2-dimethoxyethane (DME) ternary mixtures has been measured at different temperatures ranging from -10 to 80degreesC, and over the entire composition range. The experimental data have been used to check the validity of some relationships accounting for the dependence of the density on temperature and composition domains. Starting from the primary data, some derived quantities, such as excess molar volumes V-E, partial molar volumes (V) over bar (i) and partial excess molar volumes (V) over bar (E)(i), have been obtained. In these mixtures, V-E is always positive for the [CE(1) + ME(2)] binaries, while it is generally negative at all other experimental conditions, showing the greatest deviations along the binary axes corresponding to the binary subsystems in the sequence [CE(1) + DME(2)] < [CE(1) + ME(2)] < [ME(1) + DME(2)]. The results are compared and discussed to in terms of changes in molecular association and structural effects in these solvent systems.
