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)4α 3/4exp(−1.688×105/RT). The self-accelerating decomposition temperature and critical temperature of the thermal explosion are 163.3 and 174.8 °C, 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 °C. Adiabatic time-to-explosion was also estimated as 23.2 s. [Cu(en)2H2O](FOX-7)2·H2O is less sensitive.
