| Abstract: | In this paper, an attempt has been made to compare the catalytic activity of zeolites of the types NaX, NaY and NaZSM-5 and their protonated forms with some conventional Lewis acids such as anhydrous ZnCI2, AlCl3 and H2SO4 in the esterification reaction between isoamyl alcohol and acetic acid in liquid phase. The product has been analysed by chemical methods and confirmed· by FTIR and 1H NMR spectral studies. The percentage of ester in the reaction product has been estimated using gas chromatographic technique. It is observed that zeolites are more active than the conventional Lewis acids in catalysing this reaction and among the zeolites HZSM-5 resulted in 100% yield of the ester in the product extract. Selectivity for ester formation has also been found to be 100%. |
