Abstract

A series of binary mixtures of adipic acid (AA) and erythritol (Ery) were prepared and the thermal properties were investigated in this study. The results showed that a eutectic mixture was formed when the mass ratio of adipic acid and erythritol reached 1:7. The eutectic mixture displayed a melting point of 110.64 °C while maintaining a high latent heat of fusion ( Hsl = 270J/g). After 8 heating/cooling cycles, the mixture reacted to an ester according to a Fourier transform infrared (FT-IR) spectroscopic analysis. It confirmed the esterification reaction. The new material still has a high melting enthalpy (>240J/g).
