Kinetics Investigation of Solvent Polarity on Reaction Rate for Solvolysis of Ethyl Caprylate Ester in Binary Solvent System
The kinetics of alkali catalyzed hydrolysis of ethyl caprylate water-acetone mixture has been studied at different range of temperature 20 to 40°c. and covering composition range of 30 to 70% (v/v) of Acetone. With increasing composition of solvent, it has been observed to decrease in reaction rate. Activation energy has been found decreases with increasing percentage of acetone content of the medium. The influence of water and dielectric constant on reaction rate has been also studied. The thermodynamic parameters (ΔG*, ΔH* & ΔS*) has been determined which showed strong dependency on solvent composition.
