A kinetics study of palm oil methanolysis was conducted at three different temperatures and three different concentrations of catalyst; sodium hydroxide; keeping constant the molar ratio of methanol to oil and the rotational speed of the impeller (6:1 and 400 rpm). The maximum conversion of palm oil and productivity to methyl esters were obtained at 60°C and 1 wt% of NaOH based on palm oil; and they were 100 and 97.6%; respectively. The statistical analysis of conversions of palm oil and productivities to methyl esters as functions of temperature and concentration of catalyst; after 80 min of reaction; allowed them to fit second order polynomial equations; which adequately describe the experimental behavior. The experimental data appear to be a good fit into a second order kinetic model for the three stepwise reactions; and the reaction rate constants and the activation energies were determined. In this article we present the kinetic constant and activation energies for the experiments with 0.2% wt of NaOH. The effect of molar ratio on the concentration of products was investigated; while the temperature (55°C); the concentration of catalyst (0.60 wt% of NaOH); and the rotational speed (400 rpm); were held constant. The results showed that the conversion and the productivity increased due to methanol excess; and were higher for the reactions with a molar ratio of 6:1. © 2007 AOCS;
