| Abstract: | The thermal decomposition of a series of compounds has been studied by thermogravimetry, mass spectrometry, nuclear magnetic
resonance and elemental analysis. The combined use of mass spectrometry and thermogravimetry (MS and TG) in the analysis of
these compounds has allowed characterization of the fragmentation pattern which was the objective of this research. The gaseous
products, volatile condensed products and solid residues were identified by NMR and MS. Based on the product of thermal decomposition,
the mechanism of thermal decomposition has been derived. |
