Effect of Molar Ratio
The effect of the molar ratio was studied at 55 C and 0.6 wt% of NaOH, because from these values of temperature and concentration of catalyst there were not great differences in concentrations of raw materials and products during palm oil methanolysis, conversion is maximum (100%) and productivity is only 1.4% smaller to the higher obtained in this study. Concentration of methyl esters increased when the molar ratio changed from the stoichiometry to 6:1, while monoglycerides concentration diminished. As a consequence, the conversion of palm oil and the productivity to methyl esters increased with the excess of methanol. For instance, at 4 min of reaction, methyl ester concentration increased from 54 to 69 wt%
