【 摘 要 】

The ultrasonic velocity, density and viscosity in the mixtures of Cetylpyridinium Chloride (CPC) with Water - Alcohols (Methanol, Ethanol and 1-Propanol) in different concentration ranges are measured at different temperatures 303, 313 and 323K with a view to determine the Critical Micelle Concentration (CMC). From the experimental data, other related acoustical parameters such as adiabatic compressibility (β), intermolecular free length (Lf), internal pressure (i), free volume (Vf), cohesive energy (CE), relaxation time (), Rao’s constant (Ra),absorption coefficient (α/f2), acoustical impedance (Za) and solvation number (Sn) have been evaluated. All these parameters have utilized to study of various molecular interactions takes place in binary mixtures of (i) CPC + Water - Methanol, (ii) CPC + Water - Ethanol and (iii) CPC + Water -1- Propanol solution. The Critical Micelle Concentration (CMC) of (Cetyl Pyridinium Chloride (CPC) with Water - Alcohols) was determined to be 0.6%ofCetyl Pyridinium Chloride (CPC) with Water–Methanol and Water -Ethanol, 0.8% of Cetyl Pyridinium Chloride (CPC) with Water -1- Propanol system. The UV and FTIR studies were also used to characterize these samples. The results are discussed in molecular interactions, absorption and functional groups.
