Abstract
In the present work, ultrasonic parameters like velocity and attenuation are measured in mixtures of n-propyl and isopropyl alcohols in nitrobenzene at a 10 MHz pulse-echo technique. Ultrasonic attenuation is sensitive to the chemical composition of the mixture. Ultrasonic velocity and attenuation measurements using the pulse_echo technique operated at 10 MHz have been taken at various concentrations of both alcohols in nitrobenzene, from 283.15K - 293.15K. The data is analysed based on the findings, which showed that both systems exhibit critical nature and non-linear variation in ultrasonic propagation velocity and attenuation. In comparison to isopropyl alcohol in nitrobenzene, ultrasonic attenuation at lower concentrations of n-propyl alcohol in nitrobenzene reveals the dominant structural relaxation. Mixing of associated and non-associated liquids leads to dipole-induced interactions.
