Synthetic methods of benzyl acetate using different catalysts such as strong acid cation exchange resins, inorganic salts (the weight ratio
of FeCl3 to carbon (46 %) and Fe2(SO4)3), inorganic acids (H2SO4) heteropoly compounds ((NH4)6[MnMo9O32]∙8H2O), heteropolyacids
(phosphotungstic acid), solid superacids (S2O8

hydrosulfate and 1-methyl-3-(3-sulfopropyl)imidazolium tungstophosphate) have been reviewed. The above mentioned catalysts
improved the yield of benzyl acetate. These methods have the advantage of simple process and low investment costs.
