| Abstract: | The results of a new
experimental study of thermo physical properties for eight binary systems of
cinnamaldehyde with different alkanols have been presented. Speed of ultrasound
(u), density ( ) and viscosity ( ) at 303.15 K and atmospheric pressure have been measured over the
whole range of composition. These properties have been used to calculate various
thermo acoustical parameters. The variations in these parameters have been studied
in terms of nature and extent of interaction and the effect of structure of
alcohols on the existing interactions. The non-ideal behaviour of the binary
systems has been revealed through the sign and magnitude of excess velocity,
viscosity deviation and other excess parameters. These parameters have been studied
on the basis of dipole-dipole interactions and hydrogen bonding. The excess
parameters have been fitted to polynomial type Redlich-Kister equation and the
coefficients of the fitting have been found to support the present
investigation.
