摘　　要：对氧化铝碳热还原氯化法制低价氯化铝的反应进行了热力学研究,经过热力学计算得到:在常压下,该反应发生的起点温度为2121.21K,而当系统压力下降时,该反应的起点温度也会下降;经过计算得到了该反应起点温度与系统压力间的关系,也得到了不同系统压力下反应吉布斯自由能与系统温度间的关系。In this paper, the Thermodynamic study on the reaction of producing aluminum subchlofide by carbotherrnic reduction and chlorination of alumina has been carried out. After thermodynamic calculation, the conclusion that under normal pressure, the initial temperature of the reaction is 2121.21K, but when the system pressure drops, the initial temperature of the reaction will drop has been drawn, and after thermodynamic calculation, the relationship between system pressure and the initial temperature of the reaction has been obtained, and also the relationship between system temperature and the Gibbs free energy of the reaction under different system pressures.
