Naphthyl acetate was synthesized in yield of 96.8% using sodium bisulfate as catalyst. The optimum conditions were as follows: β naphthol 3 6 g, acetic anhydride 3 mL, sodium bisulfate 0 5 g , temperature 80 ℃, reaction time 40 min . The method has advantages of cheapness and simplicity , and the catalyst can be easily regenerated.
