摘　　要：通过TG-DTA-MS联用技术研究了草酸铜对高氯酸铵的催化过程。研究发现,草酸铜分解生成的氧化铜对高氯酸铵有较强的催化作用,添加2%的草酸铜使高氯酸铵的高温分解温度提前112℃。分解的气相产物主要有H2O,NH3,O2,HCl,Cl2,HNO,NO,N2O和NO2。在草酸铜原位分解生成的CuO表面吸附生成氧的过氧化离子(O2-)和氧离子(O-,O2-)是加速AP热分解反应的主要原因。In situ catalytic thermal decomposition of ammonium perchlorate has been investigated over CuC2O4.The catalytic activity measurements were carried out by TG-DTA-MS.The results revealed that the CuC2O4 had effective catalysis on the thermal decomposition of AP.Adding 2% of CuC2O4 to AP decreased the higher temperature of thermal decomposition by 112 ℃.Gaseous products of thermal decomposition of AP were H2O,NH3,O2,HCl,Cl2,HNO,NO,N2O and NO2.The mechanism of catalytic action was based on the presence of superoxide ion（O2-） and oxygenic ion（O-,O2-） on the surface of CuO.
