An investigation on the kinetics and mechanism of the thermal decomposition of GAP

The whole process of the thermal decomposition of GAP was investigated by using DSC, TGA, pyrolysis-MS, TG-FTIR, insitu pyrolysis-FTIR coupling techniques. With the thermal decomposition of GAP, N2,NH3,HCN,H2CCO,CO,CO2,C2H4 and HCHO are detected in gas phase by TG-DTG-FTIR and thermolysis-MS coupling techniques. Meanwhile, the -N3 groups disappear first and form  (CH)R(NH)( imine)  in condensed phase. Kinetic parametes of decomposition were obtained and possible thermal decomposition mechanisms were suggested.
