Resumo

In the present study, phase diagrams of two systems, formed by tristearin (1,3-di(octadecanoyloxy)propan-2yl octadecanoate) with refined rice bran oil or refined palm oil, were obtained by Differential Scanning Calorimetry (DSC) and reported in the literature for the first time. The X-ray diffraction technique was employed to verify the crystallization behavior of the individual components and for the mixture tristearin plus refined palm oil. The UNIFAC model was successfully used to predict the liquidus line of these systems, with a root-mean-square deviation between the experimental and calculated melting temperatures below 1.3%. (AU)
