Study of Soybean Oil Hydrolysis Catalyzed by Thermomyces lanuginosus Lipase and Its Application to Biodiesel Production via Hydroesterification
Table 3
Esterification reactions of FFAs of soybean oil. The reactions were carried out using a molar ratio of FFAs/alcohol of 1:3 for methanol and 1:4 for ethanol, 20% (w/w of FFAs) of the catalyst niobic acid in pellets, at 200ºC and 1 hour reaction time.
