Study of acoustical parameters of bioactive compound with benzyl propionate using ultrasonic technique

Ultrasonic technique has been found very fruitful in finding physico-chemical behaviour of binary liquid mixtures. In this present study, the thermo-acoustical parameters of curcumin with benzyl propionate have been found using ultrasonic velocity (U), density(ρ), and viscosity(η) at a room temperature of 308K. Benzyl propionate is a liquid with a sweet, fruity odour, which is used in perfumery for floral, fruity notes and in fruit flavour compositions. Curcumin, a primary bioactive substance present in turmeric, helps in the metabolic disorder, joint inflammation and nervousness. Derived parameters like adiabatic compressibility (βa), intermolecular free length (Lf), relaxation time (τ), acoustic impedance (Z) , Gibb’s energy (ΔG), acoustical impedance (Z), surface tension (σ) and attenuation coefficient (αf2). The type of interaction has been reported using these values.
