A few of synthetic methods of isoamyl benzoate using different catalysts such as sulfonic acid (p-toluene-sulfonic acid and aryl sulphonic acid), inorganic salt (NH4Fe(SO4)2∙12H2O, NaHSO4∙H2O, Fe2(SO4)3 ∙xH2O and FeCl3∙6H2O), heteropolyacid (H4O40W12 and TiSiW12O40/TiO2) and solid super acid (Ti(SO4)2/TiO2 and Zr(SO4)2∙4H2O) have been discussed in the present paper. The yields of isoamyl benzoate have been improved by the addition of above catalysts. Due to simple process and low investment cost these methods are having an advantage over other conventional methods
