MOLECULAR INTERACTION STUDIES OF PHENOL WITH ACETALDEHYDE USING ULTRASONIC AND FTIR TECHNIQUE

Abstract

The densities ( ), viscosities ( ) and ultrasonic velocities (U) were measured for the binary mixtures of Phenol with Acetaldehyde at 303K.Excess volumes (VmE), isentropic compressibilities (ksE) and isentropic compressibilities (ksE) were determined from these experimental findings. To obtain their coefficients and standard deviations, the excess or deviation properties were based on Redlich-Kister polynomial equation. Depending on the molecular interactions between the components of hetero molecules, the excess or deviation properties were considered either negative, and the nature of liquid mixtures was studied in terms of molecular interactions by steric and electronic effects. The FTIR provides support to thermodynamic studies to classify different interactions between molecules that are unlike them.
