| Outline of Final Research Achievements |
In this study, in order to evaluate the thermal hazard of oxidation appropriately, the effect on the exothermic behavior of the oxidation from metal ions and fine particles, which might be produced by the reaction of an oxidizer with a sample container, was investigated. The oxidation of tertiary pyridine resin with nitric acid was investigated in this study. It was found that the oxide of iron was produced by the reaction of an oxidizer with a stainless sample container and its oxide removed from the surface of the sample container, and its oxide affects the measurement results of the onset temperature and the generating heat quantity of the oxidation. Moreover, it was found that the contamination of the oxide of iron with a sample could be prevented by inserting the inner glass liner vessel to the sample container.
