Solid liquid phase diagrams of six binary mixtures composed by trilaurin plus fatty acids (myristic acid, palmitic acid and stearic acid) and trilaurin plus fatty alcohols (1-tetradecanol, 1-hexadecanol and 1-octadecanol) were studied by differential scanning calorimetry (DSC) and some mixtures by optical microscopy. The experimental data showed that all the studied systems present an eutectic point. Trilaurin + 1-tetradecanol and trilaurin + 1-hexadecanol systems exhibited a partial formation of solid solution. Experimental data were used to adjust the parameters of the three-suffix Margules and NRTL models and the results showed that these models can appropriately describe the liquidus lines of above mentioned systems.
