Hydrolysis of ethyl acetate in hydrochloric acid solutions containing mannitol

Authors


Abstract

Hydrolysis of ethyl acetate in 0.05 N-HCl at 25°, 30°, 35°, and 40° C was carried out in the absence and presence of mannitol. The addition of mannitol lowers the velocity constant while the activation energy remains constant. The reaction is accompanied by reduction of the entropy of activation as a consequence of solvation effects. The results agree with Laidler's theory of electrostatic interaction.
