| 摘 要： | The thermal behavior and non-isothermal decomposition kinetics of Cu（en）2H2O]（FOX-7）2·H2O （en=ethylenediamine） were studied with DSC and TG-DTG methods.The kinetic equation of the exothermal process is dα/dt=（10^17.92/β）4α^3/4exp（-1.688×10^5/RT）.The self-accelerating decomposition temperature and critical temperature of the thermal explosion are 163.3 and 174.8 ℃,respectively.The specific heat capacity of Cu（en）2H2O]（FOX-7）2·H2O was determined with a micro-DSC method,with a molar heat capacity of 661.6 J·mol^-1·K^-1 at 25 ℃.Adiabatic time-to-explosion was also estimated as 23.2 s.Cu（en）2H2O]（FOX-7）2·H2O is less sensitive.

| Abstract: | The thermal behavior and non-isothermal decomposition kinetics of Cu(en)2H2O](FOX-7)2·H2O (en=ethylenediamine) were studied with DSC and TG-DTG methods. The kinetic equation of the exothermal process is dα/dt=(1017.92/β)4α3/4exp(-1.688×105/RT). The self-accelerating decomposition temperature and critical temperature of the thermal explosion are 163.3 and 174.8℃, respectively. The specific heat capacity of Cu(en)2H2O](FOX-7)2·H2O was determined with a micro-DSC method, with a molar heat capacity of 661.6 J·mol-1·K-1 at 25℃. Adiabatic time-to-explosion was also estimated as 23.2 s. Cu(en)2H2O](FOX-7)2·H2O is less sensitive. |
