| Abstract: | The ultrasonic
velocity of the ternary mixtures ethanol+water+1-propanol at the range 288.15–323.15
K and atmospheric pressure, has been measured over the whole concentration
range. The corresponding change of isentropic compressibility was computed
from the experimental data. The results were fitted by means of a temperature
dependent equation, such parameters being gathered. The obtained experimental
values indicate varying extent of interstitial accommodation among unlike
molecules as a function of steric hindrance attending to 1-propanol composition
as key component and as a function of hydrogen bond and temperature attending
to ethanol composition as key component. |
