摘　　要：研究了高温熔融状态下氯化钾与硼酸在水蒸汽气氛下的反应。考察了不同温度,不同的硼酸与氯化钾配比时的反应状况,获得了以氯化钾中氯根反应的转化率为指标的反应较优条件,以及氯化钾与硼酸直接反应制取硼酸钾盐的宏观动力学。结果表明,该反应在750℃时为二级反应,而在850℃变为一级反应。The molten hydrolysis reaction of potassium chloride and boric acid at high temperature was investigated. The reaction conditions, including the reaction temperature, the mole ratio of boric acid and potassium chloride, were studied. Macrokinetics of the first-order reaction at 750°C and the second-order reaction at 850 C were obtained based on the experimental results.
