在３４３～３６３Ｋ、硫酸与氯化钾摩尔比为１．２∶１、硫酸浓度在５５％～７５％的条件下，通过实验研究了硫酸分解氯化钾的反应动力学，结果表明：转化反应受化学反应控制、其表观活化能为７２．７５ｋＪ／ｍｏｌ，相应反应速率的数学模型为：－ｌｎ（１－ｘ）＝３．９０９×１０－４×ｅｘｐ（－７２．７５／ＲＴ）·ｔ
The reaction kinetics of potassium chloride decomposition by sulfuric acid was studied experimentally at 343-363 K with sulfuric acid to potassium chloride molar ratio of 1.2: 1 and sulfuric acid concentration of 55% -75%. The results showed that the conversion reaction Under the control of chemical reaction, the apparent activation energy was 72.75 kJ / mol and the corresponding reaction rate was: -ln (1-x) = 3.909 × 10-4 × exp (-72.75 / RT) · T
