The differential equations system was solved utilizing Runge Kutta’s method of the fourth order. The rate constants were obtained after a minimizing process of the summed squared error. Two scenarios were taken into account: the first one without including associated that allow a good curve fitting were found. In the reactions at 55 and 60 C and concentrations of NaOH 0.6 and 1 wt%, the presence of palm oil and diglycerides after 20 min were not detected. Based on the previous results and assuming that after this time the reaction gets closer to equilibrium and therefore the reaction rate is zero, it was concluded that the kinetics constants for the reactions DG?TG and MG?DG, k–1 and k–2, are equal to zero.
