Non-isothermal Decomposition Kinetics of [Cu(en)2H2O](FOX-7)2·H2O

doi:10.1007/s40242-014-3549-5

Abstract

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=(10^17.92/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℃, 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^-1at 25℃. Adiabatic time-to-explosion was also estimated as 23.2 s. [Cu(en)₂H₂O](FOX-7)₂·H₂O is less sensitive.

Key words: 1,1-Diamino-2,2-dinitroethylene(FOX-7), Copper complex, Non-isothermal decomposition kinetics, Thermal property
