Abstract: | Densities at 293.15, 298.15,
303.15, 308.15 and 313.15 K of the binary liquid mixtures made of tert-butyl ethyl ether with either 2-ethoxyethanol,
or 2-(2-ethoxy)ethoxyethanol, or 2-2-(2-ethoxy)ethoxy]ethoxyethanol have
been measured over the whole mixture compositions. These data have been used
to compute the excess molar volumes (VE).
The excess molar volumes always are negative over the entire range of composition
for all the binary mixtures investigated. 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 possible intermolecular
interactions. |
