| Abstract: | The condition in synthesis of benzyl acetate catalyzed with sodium bisulfate monohydrate (NaHSO 4·H 2O) was discussed. Synthesis of benzyl formate, benzyl acetate, benzyl propionate and benzyl butyrate under amount of substance ratio of carboxylic acid, benzyl alcohol and sodium bisulfate were 3∶2∶0.145, with cyclohexane as solvent, and using refluxing and water segrating. The yields of esters are 68.5%～84.1%. |
