Abstract

Fatty acids, fatty alcohol compounds and triacylglycerols (TAGs) present a significant role in industrial applications, mainly in food, cosmetics and pharmaceutical industries. In this study, eight solid-liquid phase diagrams composed by tripalmitin plus fatty acids (capric acid, lauric acid, myristic acid, palmitic acid and stearic acid) and tripalmitin plus fatty alcohol compounds (1-decanol, 1-dodecanol and 1-tetradecanol) were studied using Differential Scanning Calorimetry (DSC) technique, optical microscopy and X-ray analysis. The phase diagrams formed by tripalmitin + fatty acids (myristic acid, palmitic acid and stearic acid), present a eutectic behavior with a solid solution for tripalmitin (1) + myristic acid (4) system, and a monotectic behavior for tripalmitin + (capric acid and lauric acid) whereas the phase diagrams formed by tripalmitin + fatty alcohol compounds present a monotectic behavior and just one of them present a monotectic behavior with a solid solution (1-tetradecanol). The liquid phase was modelled using ideal assumption, 3-suffix Margules and NRTL models, adjusting its parameters. These models described properly the liquidus line of the systems studied.
