4. Conclusions
This work studied the production of FAEE from corn oil by enzymatic catalysis with Lipozyme TL IM
from Novozymes, using absolute ethanol as reagent. Results show that the best operating conditions
are an oil/ alcohol molar ratio of 1:6, a catalyst/ oil mass ratio of 2.8 wt%, a reaction time of 12 h and a
reaction temperature of 35 ºC. For these conditions it is possible to obtain a reaction yield of 98.95 wt%
with a FAEE content of 69.2 wt%, being linoleate (C18:2) and oleate (C18:1) the most significant esters
(with relative percentages of 42.97 wt% and 22.54 wt% respectively). The quality of biodiesel was also
assessed, according to the most important parameters defined in the EN14214:2009 standard.
