Abstract

The effects of the type of storage atmosphere used on the spontaneous ignition of cellulose nitrate (NC) were investigated. Nitrogen dioxide, nitric oxide, oxygen, nitrogen, and dried air were used as storage atmospheres. Exothermic degradation was observed to be acceleratd in oxygen. In contrast, no degradation was observed with nitrogen. These results indicate that exothermic degradation by oxygen is related to spontaneous ignition. In addition, when low concentrations of nitrogen dioxide were used, there was no exothermic degradation. These results suggest that nitrogen dioxide contributes little to the generation of heat.
