Effect of nano-catalysts on the thermal decomposition of aminonitrobenzodifuroxan

The effect of nano-catalyists (Al₂O₃, Fe ₂O₃, TiO₂, SnO₂) on the decomposition of aminonitrobenzodifuroxane is studied by DSC and TG. The results show that four nano-catalysts all decrease its onset decomposition temperature and increase its end temperature. Fe₂O₃, TiO₂ and SnO₂ not only improve quantity of releasing heat of CL-18, but make the reaction relatively stable. With the increase of their content, the temperature of the most themogravimetric rate firstly increases and then decreases, but the quantity of the last solid residual always decreases. SnO₂ and Al₂O₃ respectively make the first activation energy decrease 13. 18 kj/mol and 16. 25 kj/mol, and make the second activation energy decrease 40. 49 kj/mol and 43. 96 kj/mol. However, Fe ₂O₃ only has an effect on the second activation energy and make it decrease 40. 41 kj/mol.
