Benzyl benzoate naturally exists in Peru balsam, tuberose, carnation and tolu balsam, etc. It is usually produced by chemical synthesis in industry.

Add 7g (0.07mol) of benzyl alcohol into a 100mL round bottom flask, add 0.3g (0.013mol) of sodium metal within 30min to dissolve in it, and after cooling to room temperature, slowly add 45.4g (0.43mol) of benzaldehyde In the 250mL three-necked bottle. The mixture generates heat due to the reaction and is cooled with water so that the temperature does not exceed 50-60°C. After about 30 minutes, when the temperature stops rising, heat in a water bath to continue the reaction for 1 hour. After the reaction was cooled, 40 ml was used. Wash 2 times with water. The obtained oil is distilled under reduced pressure, first distilling benzyl alcohol, unreacted benzaldehyde and a small amount of water, and then collecting the fraction at 184-185°C (2kPa) to obtain about 40g of product.

Benzyl alcohol and ethyl benzoate are transesterified in the presence of sodium carbonate. After the reaction, the ethanol is distilled off under normal pressure, and then benzyl alcohol is distilled off under reduced pressure. After cooling, it is washed with water, layered, dried, and finally distilled under reduced pressure to obtain the product.

Under stirring and cooling conditions, dissolve sodium in benzyl alcohol, then slowly add benzaldehyde, heat on a water bath for 1 to 2 hours after the effect is complete, separate the precipitated oil layer, wash and fractionate it.

Benzyl alcohol is esterified with benzoic acid.

It is obtained by fractional distillation after transesterification of methyl benzoate with benzyl alcohol using sodium carbonate as a catalyst.

Sodium benzyl alkoxide is heated to react with benzaldehyde, or sodium benzoate is reacted with benzyl chloride. In the perfume industry, ethyl benzoate and benzyl alcohol are used for transesterification.
