Abstract
Eugenyl acetate is used in various industries including the pharmaceutical industry, the food and beverage industry, the vegetable pesticide industry, as well as a bio-additive fuel. Eugenyl acetate can be obtained synthetically by esterification of eugenol and acetic acid using an acid catalyst. The purpose of this study was to examine the heterogeneous catalyst CsTPA supported by fly ash for the esterification reaction of eugenol to eugenyl acetate. CsTPA was prepared at the impregnation time (4,8, and 12 hours) and the calcination temperature (300, 400 and 500°C). Calcination temperature and impregnation time have little effect on the catalytic structure, except on the porosity of the solid catalyst. The catalytic activity was conducted by synthesizing eugenyl acetate. The conversion results for eugenyl acetate were not substantially different at about 75-80 per cent. CSTPA/fly ash tends to be an alternate solid catalyst for eugenyl acetate production.
