The product has been analysed by chemical methods and confirmed· by FTIR and <sup>1</sup>H 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%.</span>
