Volumetric properties of binary mixtures of alkoxyethanols with ethyl tert-butyl ether at various temperatures

Densities at T = (293.15, 298.15, 303.15, 308.15, and 313.15) K in the binary liquid mixtures of ethyl tert-butyl ether with 2-methoxyethanol, 2-(2-methoxyethoxy)ethanol or 2-{2-(2-methoxyethoxy)ethoxy}ethanol have been measured over the entire mixture compositions. These data have been used to compute the excess molar volumes. The excess molar volumes are negative over the entire range of composition for all mixtures. The changes of VE with variations of the composition and the chain-length of the alkyl groups in the alkoxyethanol molecules are discussed in terms of intermolecular interactions.
