| Outline of Final Research Achievements |
In this study, we investigated the thermal behavior of nitrocellulose (NC) containing acid solution (nitric acid/NC or sulfuric acid/NC) in sample containers of various volumes, by using thermal analysis. In the case of sulfuric acid/NC, the thermal stability decreased with increasing container volume. This behavior indicated that in large-volume containers, the solvent water was more rapidly vaporized and sulfuric acid solution was more concentrated than that in other containers. The NC/nitric acid showed the highest destabilization when V/M, the value of sample volume divided by sample mass, is 200~400 μL/mg. Therefore, it can be concluded that the behavior of the NC/nitric acid is perhaps caused by interaction between vaporized nitric acid promoting the NC decomposition and nitric acid solution in liquid phaze preventing it by absorbing the reaction heat.
