A survey of the literature was made in order to examine the ralationship between the chemical structure and the speed of sound in pure alcohols. Additionally, the acoustic behaviour of mixtures of methanol with some normal alcohols and with various isomers of butanol was examined. The absolute deviations of the measured sound velocity from the ideal one ("excess" velocity Delta u(x)) and the axcess adiabatic compressibilities are in most cases very small and S-shaped. A strict correlation between the shape of Delta u(x) and K E(x) for the investigated mixtures was found. A dependance of the ultrasonic behaviour of pure alcohols and their binary mixtures on the molecular structure as suggested.
