蒽/马来酐低温贮热体系的研究

Research on the chemical storage system Anthracene/Maleic anhydride at low temperature

对蒽 /马来酐作为一种低温化学贮热材料进行了热分析研究 ,实验表明该反应体系在三氯化铝作催化剂的条件下 ,其吸放热温度范围分别为 2 44-341℃ and 97.5 -1 40 .1℃ ,吸热反应焓和放热反应焓分别为 5 9.7k J· mol-1 and 39k J· mol-1 。

Chemical storage systems of Anthracene/Maleic anhydride were investigated at low temperatures by the heat analytic method. It was revealed that when the temperature of endothermic- and exothermic reaction with AlCl 3 as catalyst varies from 244-341℃ and 97.5-140.1℃ respectively. The enthalpies of endothermic- and exothermic reaction are 59.7 kJ·mol -1 and 39kJ·mol -1 respectively.
