| Abstract: |
| The technological conditions that benzyl acetate was synthesized from acetic acid and benzyl alcohol with Lewis acid zinc chloride as catalyst were studied, The results showed that the optimum reaction conditions were benzyl alcohol:acetic acid=2.0:1.0,the taking water reagent 10 ml, amount of catalyst 1.5g and yield of benzyl acetate could reach 93.2%. |
| Key words: Lewis acid flavor benzyl acetate |
