Abstract
BALUJA, Shipra and LAVA, Divyata. Ultrasonic behavior of various chalcones in some solvents at different temperatures. Rev. colomb. cienc. quim. farm. [online]. 2016, vol.45, n.3, pp.339-361. ISSN 0034-7418. https://doi.org/10.15446/rcciquifa.v45n3.62014.
Ultrasonic velocity, density and viscosity of some synthesized chalcones were measured in N,N-dimethyl formamide and chloroform at different temperatures (298.15 to 318.15 K). From these experimental data, various acoustical parameters such as specific impedance (Z), adiabatic compressibility (ks), Rao's molar sound function (Rm), intermolecular free path length (Lf), solvation number (Sn), internal pressure (Π) have been calculated in order to understand the molecular interactions in the studied solutions. The results are interpreted in terms of molecular interactions occurring in the solutions.
Keywords : Ultrasonic velocity; chalcones, acoustical parameters; DMF; chloroform.
