Thermogravimetric analysis study of a cyclic organo-phosphorus compound

Article abstract of DOI:10.1080/10426509808035676

Four methods were used to study the thermal cyclisation of 2-(2-hydroxyphenyl)-phenylphosphonous acid 3, and the results were compared with the thermal decomposition of 9,10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO). The decomposition of DOPO was found to be a simple process composed of at least one stage for which apparent activation energies can be calculated. These investigated methods were those of van Krevelen, Horowitz-Metzger, Coats-Redfern, and MacCallum-Tanner. These methodologies evaluated the similar apparent activation energies E_a for cyclisation of 3 and for decomposition of DOPO. Moreover, these apparent activation energies for decomposition of DOPO were compared with that calculated by the isothermal method.
