To determine the effect of reaction temperature on methyl
esters formation, the transesterification reaction was carried out
under the optimal conditions obtained in the previous section
(i.e. 6:1 methanol/oil molar ratio and 1.0 wt.% NaOH concentration
for neat oil; 7:1 methanol/oil molar ratio and 1.1 wt.% NaOH
concentration for UFO).
