Flash pyrolysis studies of [Co (CHZ)₃](ClO₄) ₂

The 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](ClO₄)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,NH₃,HNCO, CO₂, 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, CO₂ and H₂C = O. The concentration change curves of the main gaseous products vs. time are also put forward.
