Ultrasonic method of determination of stability constants of charge transfer complexes of certain carbonyl compounds and diethylamine in n-hexane (original) (raw)

Physics and Chemistry of Liquids, 2008

Abstract

The ultrasonic velocities (U), densities (ρ) and viscosities (η) were measured for solutions containing equimolar concentrations of diethylamine (donor), nine aldehydes and nine ketones (acceptors) in n-hexane at 303 K. Acoustical parameters such as adiabatic compressibility (β), free length (Lf), viscous relaxation time (τ), and molecular interaction parameter (χU) have been computed. These values indicate the formation of charge transfer
