The hexanitrates of the six‐carbon sugars mannitol and sorbitol were prepared and studied to gain insight in their relative stabilities. Synthesis and characterization of these materials resulted in the identification of two new crystalline polymorphs, one for each hexanitrate. Mannitol hexanitrate (MHN) exposed to elevated temperatures exhibited a different structure when measured by x‐ray diffraction (XRD) and Raman spectroscopy; however, no differences were observed in the thermal behavior. Sorbitol hexanitrate (SHN) has two distinct crystalline polymorphs that result in different melting behavior and differences in Raman and XRD. Thermal stability of these hexanitrates was also examined; despite being isomers, SHN and MHN differ in their long‐term thermal stability.

Flexible plasticized pyrotechnic formulations were developed to be used for the safe and controlled destruction of light cased chemical and biological threats. The formulations generate high heat as well as halogen if required and can be used in closed spaces without required personnel evacuation.

Among oxidizers those containing the ammonium cation have the potential of self-oxidization, making them of special hazard. Herein we examine ammonium nitrite and ammonium chlorate, two ionic compounds with well-known hazard potential, and compare their explosive performance with related materials. A novel protocol for assessment of explosivity on the gram scale is employed.
