Özet:

 


The packing
properties of hydroxylic chemicals is very unusual, however these substances
find extensive application in food and alcoholic beverage industry. When short
alcohols are mixed with water, the entropy of the final system increases far
less than we could expected for an ideal solution of ramdomly interacting
molecules. Experimental works on thermodynamics helps to understand how
hydrophobic headgroups of alcohol molecules in aqueous media cluster together.
To this aim, the densities and ultrasonic velocity of the ternary mixtures
ethanol + water + 2-propanol at 288.15-323.15 K and atmospheric pressure, have
been measured over the whole concentration range, due to the importance of the
2-propanol among the flavor compounds contained into spirit beverages. The
experimental data have been analyzed in terms of different theoretical models,
an adequate agreement between the experimental and predicted values both in
magnitude and sign being obtained, despite the high non-ideal trend. The
obtained experimental values indicate varying extent of interstitial
accommodation among unlike molecules with strong influence of steric hindrance
among aliphatic ends.
