Abstract


The kinetic study of crystallization in purification process has not been well, because the models has not adjusted the experimental data. In the system, tripalmitin - triolein with higher molar fractions at upper 40º C. Only crystallized tripalmitin. It uses two models, called Avrami and D. The model D adjusted very well the experimental data, the Avrami was not. At molar fraction 1, were not differences between two models, thus at this point, the nuclei formation was simultaneous, and in molar fractions lower than 1, the nuclei formation was continuous.
