摘　　要：应用高温传感器测定了铁在氯气中燃烧时的温度;基于实际反应温度、压强与物质状态,对铁与氯气的相关反应进行了热力学分析,发现FeCl3(Fe2Cl6)是铁与氯气反应过程中绝大多数情况下的热力学稳定产物,而铁与氯气反应生成FeCl2的条件则较为苛刻;反应的动力学分析,FeCl2和FeCl3的结构分析,也表明铁与氯气反应生成FeCl3更加有利。The temperature of Fe combustion in Cl2 was measured by high temperature sensor. Based on the actual reaction temperature, pressure and the state of matter, the thermodynamic analysis of the related reactions between Fe and Cl2 was carried out. It was found that FeCl3(Fe2Cl6) was the thermodynamic stable product in most cases of the reaction process of Fe and Cl2, but the reaction conditions of Fe and Cl2 to produce FeCl2 were more stringent. Through the kinetic analysis of the reaction and the structure analysis of FeCl2 and FeCl3, it is also concluded that the reaction of Fe and Cl2 to form FeCl3 is more favorable.
