Molecular Interactions in the Binary Mixtures of Benzyl Benzoate in Alcohols

Ultrasonic velocity, density and viscosity have been measured in the binary mixtures of alcohols with benzyl benzoate as common component at 30°C. The thermodynamic and other related parameters like isentropic compressibility, free length, internal pressure, Gibb's activation energy etc. have been computed and their excess parameters are analyzed in the light of molecular interactions between the constituent molecules in the mixture. In all the three binary mixtures, strong molecular interactions between unlike molecules are predicted besides dipole-dipole interactions. In all the three mixtures endothermic reaction appears to be prevalent.
