摘　　要：通过TG、DSC等热分析技术可以得到物质在常规热分解过程的主要固相产物。为了进一步考察[Co(CHZ)3](ClO4)2(CoCP)的热分解行为,采用T-jump/FT-IR在线分析技术测定了CoCP的快速热分解气体产物。CoCP在1atm下以一定的升温速率达到设定的温度进行快速热分解。利用其快速热分解过程的控制电压变化曲线,可以得知CoCP在快速热分解过程的吸热、放热变化情况;用快速扫描傅立叶变换红外,可以解析分解过程中逸出的12种红外活性气体。研究发现,在CoCP快速热分解过程所产生的12种气相产物中,以CO的浓度最高,NO和HCN为主要的含氮气相产物,含碳气相产物以CO,CO2和H2C=O为主;并给出了其主要气相产物的浓度随时间的变化曲线。ZThe main solid products from the conventional thermal decomposition can be determined by TG、DSC technology. To investigate the thermal decomposition behavior of [Co (CHZ)_3](ClO_4)_2 (CoCP) further, the T-jump/FT-IR spectroscopy was used to determine the main gaseous products evolved from the thermolysis of CoCP in real time. CoCP was flash-pyrolyzed to the set temperature under 1 atm. The control voltage trace can detect the thermal events occurring within the sample as it decomposes. With the help of rapid scanning Fourier transform infrared (FT-IR) spectroscopy, 12 specific IR-active gas products (NO,HCN,NH_3,HNCO,CO_2,CO,HCl and so on) were resolved during the flash pyrolysis process, of which CO is the most novel product, NO and HCN are the dominant gases containing nitrogen, the dominant gases containing carbon are CO, CO_2 and H_2C=O. The concentration change curves of the main gaseous products vs. time are also put forward.
