✦ Synopsis

The viscosities and speeds of sound of 15 binary mixtures of alkyl alkanoate methyl-or ethyl propanoate . Ž . and butanoate -hydrocarbons n-heptane, benzene, chlorobenzene and 1,1,2,2-tetrachloroethane have been measured at 308.15 K and 318.15 K. The mixture viscosities were correlated by Grunberg-Nissan, Hind and Ž . Auslander equations. The speeds of sound of all the mixtures were also predicted by free length theory FLT Ž . and collision factor theory CFT at 308.15 K. The excess isentropic compressibilities were calculated. The qualitative analysis of the excess isentropic compressibilities shows that disruption in dipolar associates of ester species by n-heptane in ester-n-heptane and the specific interactions of n-p and -O PPP PPP Cl-types in ester-benzene, -chlorobenzene and -1,1,2,2-tetrachloroethane mixtures are predominant.
