The equation proposed for non-associated liquids describes a new functional dependence of the sound velocity in these liquids on their physico-chemical characteristics (critical volume, surface tension, density and molecular mass). It is shown that this equation can be used for the adequate calculation of the sound velocity at different temperature.

L'équation, qui a été proposée pour les liquides non-associés, décrit une nouvelle relation fonctionnelle entre la vitesse du son dans ces liquides et les caractéristiques physico-chimiques de ces derniers (volume critique, tension superficielle, densité et masse moléculaire). Il a été démontré que cette équation peut être utilisée pour les calculs de la vitesse du son à différentes températures.

Key words: Sound velocity -- non-associated liquids -- physico-chemical characteristics
