To cultivate students' innovation ability,we designed the synthetic method of benzyl benzoate as an organic chemistry laboratory experiment.Benzyl benzoate was directly synthesized from benzaldehyde in the presence of a sodium benzyloxide via the Tishchenko reaction.The experimental conditions are optimized with a benzaldehyde to sodium benzyloxide mole ratio of 33:1 and a 50-60℃ reaction temperature for 1 h.A yield up to 69% was achieved with the purity higher than 99%.The experimental results show that the process is in accordance with the requirements of organic chemistry laboratory teaching.
