Ultrasonic studies on molecular interaction of benzaldehyde, cinnamaldehyde, 4-methoxy benzaldehyde and diethylamine in n-hexane solutions at 303K
ABSTRACT:
Ultrasonic velocities(U), Densities(ρ), Viscosities(η), are
measured for three different aromatic carbonyl compounds (Benzaldehyde,
Cinnamaldehyde, 4-methoxy benzaldehyde) and Diethylamine in n-hexane solutions
containing equimolar concentrations (1x10-4M to 1x10-3M) at 303K. The
interaction between solvent molecules and Carbonyl compounds - Diethyl amine
complexes are observed. Acoustical parameters such as adiabatic compressibility
(κ), free length (Lf), internal pressure(πi), cohesive energy(CE), formation
constant(K) values are also calculated. These values indicate complex formation
and ion-solvent interaction between aromatic carbonyl compounds and
diethylamine in n-hexane medium.
