The aim of this study was to evaluate the synthesis of methyl and ethyl esters of soybean using two different types of heterogeneous catalysts: mesoporous molecular sieve [CTA+]Si-MCM-41 and KF-clay. Reaction conditions using methanol were temperature of 80°C with molar ratio of 1:12 to oil/alcohol, and 1:9 to [CTA+]Si-MCM-41 and KF-clay, respectively. Reaction times ranged from 1 to 2 hours. With the application of ethanol, the catalyst mass was maintained and some conditions were changed, such as temperature at 100°C, molar ratio of 1:15 and 1:12, and reaction time of 4 hours. Catalysts were characterized by means of (BET) N2 physisorption, X-ray diffraction (XRD) and scanning electron microscopy (SEM). Conversions of ethyl esters were lower than those of methyl esters. With catalysts [CTA+]Si-MCM-41 and KF-clay, conversions of 6.4 and 63.3% by using ethanol as well as conversions of 91.0 and 95.2% with methanol were obtained.
