Über Schallkennlinien einiger binärer Mischungen und Lösungen

The relation between sound velocity, space filling factor and collision factor which has been established for pure organic liquids has been tested in the case of 23 organic mixtures and solutions. The components of the systems chosen do not contain heavy atoms. Sound velocities calculated by means of the above mentioned relation and by using Rao's expression are compared with the measured values.
