| 摘 要： | 本文用DTA-TG技术结合化学方法,研究了氯酸钾催化热分解历程。提出当用二氧化锰作催化剂时,可用中间产物理论解释,反应历程为,2 KClO_3+MnO_2K_2MnO_4+2Cl]+2O_2(慢)K_2MnO_4+2Cl]→2KCl+MnO_2+O_2(快)当用其它催化剂时,氯酸钾的两个分解放热峰峰温降低,可用活化中心理论解释。

| Abstract: | In this paper, DTA-TG technique and chemical methods are used to investigate the mechanism of catalytic thermolysis of KClO_3.We are suggested that when MnO_2 is used as a catalyst, the mechanism can be explained by medium-product theory: 2KClO_3+MnO_2K_2MnO_4+2Cl]+2O_2 (slow) K_2MnO_4+2Cl]→2KCl+MnO_2+O_2 (fast) When other catalysts are used, the two peak temperature of ana- lytic exothermal peaks of KClO_3 are lowered. these phenomena can be explained by active center theory. |
