Abstract:

The rates of thermal decomposition of six polynitropolyphenyl compounds at elevated temperatures, alone and in trinitrobenzene solutions were measured by two methods 1 thin layer chromatographic, TLC, analysis for undecomposed polynitropolyphenyl, and 2 total pressure increase due to gas evolution at constant volume. The stability at 280 C by the TLC method of analysis was found to decrease in the following order, ONT NONA TNB PENTA DODECA HNB. In general, gas evolution, was found not to be a reliable index of stability. The lack of readily oxidizable groups, lack of steric crowding, but presence of strong crystal lattice forces within the solid explosive contribute toward increased thermal stability. As a class, the polynitropolyphenyls are the most heat resistant explosives thus far studied. Author
