Partial Molar Volumes of 15-Crown-5 Ether in Mixtures of N,N-Dimethylformamide with Water
Abstract
The density of 15-crown-5 ether (15C5) solutions in the mixtures of N,Ndimethylformamide
(DMF) and water (H2O) was measured within the temperature range
293.15–308.15 K using an Anton Paar oscillatory U-tube densimeter. The results were
used to calculate the apparent molar volumes (VU) of 15C5 in the mixtures of DMF + H2O
over the whole concentration range. Using the apparent molar volumes and Redlich and
Mayer equation, the standard partial molar volumes of 15-crown-5 were calculated at
infinite dilution (V
m). The limiting apparent molar expansibilities (α) were also calculated.
The data are discussed from the point of view of the effect of concentration changes on
interactions in solution.
