Resumo

Solid-liquid equilibrium for binary mixtures of ethyl oleate and ethyl myristate, ethyl oleate and ethyl stearate, and ethyl myristate and ethyl stearate was studied through differential scanning calorimetry. Experimental results confirmed the occurrence of polymorphism of ethyl oleate, ethyl myristate and ethyl stearate. Simple eutectic behavior was observed for systems containing the unsaturated ester ethyl oleate. However, the system formed by both saturated esters (ethyl myristate and ethyl stearate) presented a complex behavior, and not only eutectic transitions but also peritectic and metatectic transformations were observed. In addition, solid-liquid equilibrium for the ternary mixture formed by the esters mentioned was studied. A peritectic reaction was also manifested in the ternary system. (C) 2014 Elsevier B.V.
