Abstract

Ultrasonic velocities (u), and densities (ρ) were measured in aqueous and n-hexane solutions of 1-propanol and 2-propanol (positional isomers) at various concentrations and in the temperature range 20-40°C. Acoustical parameters such as adiabatic compressibility (β), intermolecular free length (L_f), available volume (V_a) and characteristic impedance (Z) were calculated to differentiate these position isomers. There is significant difference in the acoustical and thermodynamic parameters of the two alcohols in aqueous and hexane solutions in the temperature range investigated.

Keywords
