摘要

In general, esterification reactions are favored by the increase in reaction temperature, excess of one of the reactants (usually alcohol), and additions of acid or basis catalysts. Esterification of oleic acid with methanol catalyzed by Nb2O5·nH2O calcined at different temperatures showed good conversion rates, especially at reaction temperature of 100°C and higher catalyst proportions. PLS calibration showed good results for predicting the amounts of methyl oleate in reaction products.
