Özet
In this study, xylitol penta myristate and xylitol penta laurate were prepared as novel solid-liquid phase change material by means of esterification reaction. These esters were characterized chemically using a Fourier transform infrared spectroscopy method. By using a differential scanning calorimetry method, the melting temperatures of xylitol penta myristate and xylitol penta laurate were measured as 50.28 and 43.53°C, respectively, while their latent heat values were determined as 199.50 and 184.71 J/g, respectively. These results indicated that the synthesized esters had high latent heat of melting and suitable phase change temperatures for thermal energy storage applications. A thermal cycling test showed that the synthesized phase change materials had good thermal reliability after thermal 100 melting-freezing cycles. Thermogravimetric analysis results also revealed that the phase change materials have good thermal stability over their working temperatures.
