A Study of Structure Characterization and Thermal Decomposition of the Impurities of HNIW

LIU Jin-quan,OU Yu-xiang,WANG Yan-fei,MENG Zheng,WU Xiang-guo(College of Materials Science and Engineering,Beijing Institute of Technology, Beijing 100081,China)  
HNIW was respectively synthesized with TADBIW by use of a sub-nitrolysis/nitrolysis one-pot method and with TADFIW by use of a mixed acid method.The main impurities of HNIW were separated using a column chromatography and confirmed as PNMAIW and PNMFIW via FTIR,(()~1H NMR,) MS and element analysis.The DSC and kinetics calculations show that the initial and peak decomposition temperatures of PNMFIW are higher than those of PNMAIW and the apparent decomposition active energy of the former is twice as much as that of the latter.The reason maybe is that the formyl on the hexabasic ring is more stable than the acetyl on the pentabasic ring to the cage structure for PNIW with one substituting group.
