Abstract
Densities, viscosities and speed of sound of binary mixture of
1,3-Dioxolane with Pentanol, Hexanol, Heptanol, Octanol, Nonanol and Decanol
have been measured over the entire range of composition at temperature 298.15K.
From the experimental densities, viscosities and speed of sound, the excess sound velocity (uE),
excess molar volume (VmE), and excess viscosity (ηE)
have been investigated have been calculated. The present paper represents the
nonlinear variation of ultrasonic velocity lead to dipole –dipole interactions
between unlike molecules through hydrogen bonding and positive values indicate
that the effect due to breaking up of self-associated structures of the
components of the mixtures is dominant over the effect of H-bonding and
dipole-dipole interaction between unlike molecules. The deviation has been
fitted by a Redlich-Kister polynomial equation and the results are discussed in
terms of molecular interactions. The excess properties are found to be eighter
negative or positive depending on the molecular interactions and nature of the
liquid mixtures. Excess properties provide important information in
understanding the solute-solvent interaction in a solution.
