摘要：The density, speed of the sound and viscosity were measured for solutions containing equimolar concentrations ofthe ternary mixtures consists of Pyridine as donor with Cyclohexanone, Acetone, Acetophenone and Ethyl methylketone as an acceptors separately in n-hexane solvent including pure liquids at 303K. Acoustical andthermodynamic parameters like acoustical impedance (Z), sound velocity (U), internal pressure (πi), Intermolecularfree length (Lf) and adiabatic compressibility (ß), Formation Constant (K) have been evaluated. The constant valuesof free energy of formation (ΔG#) and relaxation time () indicates that the formation of similar type of complexesin these systems. The variation in free energy of formation (ΔG0F) values suggests that their thermodynamic stabilitydepends on the structure of donor and acceptor.
