There is an increase in the inclination of chemical industries towards new processes that should meet the requirements such as the generation of nearly zero waste chemicals, less energy and sufficient use of product chemicals in various applications. Esterification is one of the most widely employed reactions in the organic process industry. Most esterification reactions employ liquid acids as catalysts that cannot be recovered and also tend to corrode the reactors. This necessitates the use of heterogeneous eco-friendly catalysts. The present work focuses on the synthesis of isoamyl acetate using silica supported heteropoly acid. The catalyst was prepared by precipitation method. The performance of the catalyst was studied for the synthesis of isoamyl acetate at various reaction conditions such as mole ratio of reactants, temperature and catalyst loading. It was observed maximum acetic acid conversion of 90% was attained at 100oC, 1:3 and 3w/w% catalyst loading. Further, the kinetic studies were done and the activation energy was determined by the Arhennius equation as 33.76 kJ/mol.
