Ft-Ir Spectroscopic Study Of Excess Thermodynamic And Transport Properties Of Liquid Mixtures Of P-Chloroacetophenone With Alkoxyalkanols

Densities, speeds of sound and viscosities were measured for the binary mixtures para-chloroacetophenone (PCAP) with 2-alkoxyethanols (2-methoxyethanol [2-MOE], 2-ethoxyethanol [2-EOE] and 2-butoxyethanol [2-BOE]) at T = (303.15-318.15) K. These experimental data have been used to calculate excess volume (V-E), excess isentropic compressibility (Ks(E)), deviation in viscosity ( increment eta) and excess Gibbs free energy of activation of viscous flow (G(*E)). The excess parameters have been fitted to the Redlich-Kister equation and the results were analysed in terms of acid-base interactions, hydrogen bond interactions and dipole-dipole interactions between unlike molecules. Further, the FTIR spectra have been recorded at 298.15 K and found to be useful for understanding the presence of hydrogen bonding between oxygen atom of carbonyl group of p-chloroacetophenone and hydrogen atom of the -OH group of 2-alkoxyethanols molecules in the present liquid mixtures. A good agreement is obtained between excess quantities and spectroscopic data.
