| Abstract: | Apparent molar volumes ( )
of dilute solutions of triethylamine in heptane, 2-butanone, ethyl
ethanoate, butyl ethanoate, 1,4-dimethylbenzene, ethylbenzene, chlorobenzene,
and nitrobenzene, at 303.15 K have been calculated from the densities
determined. The
limiting partial molar volumes ( ),
limiting excess partial molar volumes ( )
and volumes of transference ( )
from heptane to the other investigated solvents of
varying polarity have been analysed in terms of solute-solute-solvent interactions and structural effects of the molecules. Using
the Terasawa model, an
attempt has been made to find a measure of the
contribution of specific interactions in terms of void volumes of triethylamine
in the investigated solvents over a range of polarity. The Flory theory/ERAS model has also been applied
to estimate the apparent molar volumes, excess apparent molar volumes and
limiting excess partial molar volumes of triethylamine in investigated systems. |
