Enabling methods in next-generation energetic materials synthesis
Abstract
Energetic materials chemistry encompasses all of propellants, explosives and pyrotechnics; metastable compounds or mixtures capable,of releasing stored energy. This nature of these materials results in one of the fundamental challenges of the field, the ability to, produce a material capable of releasing large amounts of energy, yet being of sufficient stability for safe handling and only relea,sing stored energy when desired. Unfortunately, this issue becomes more pronounced when the extremes of energetic performance are so,ught; in many cases, the highest-performing energetic materials are also the most sensitive to mechanical, thermal, or electrical st,imuli. Creation of energetic materials with high performance while possessing high degrees of insensitivity towards these types of s,timuli is a major goal of the proposed research. However, practical issues are also encountered when such designer energetics are co,nsidered; long syntheses can preclude use and the synthetic pathway used toreach the energetic must be amenable to scaleup. In order, to meet these goals, new strategies are needed for the synthesis of energetics, whether new methods for the incorporation of the ni,tro group or new methods to create the nitrogen rich heterocycles that make up the backbones of a variety of energetic materials. Th,e proposed research will meet the goals of the Advanced Energetic Materials program in two major ways: strategies to build up energe,tic heterocycles will be explored with a focus on less explored heterocycles will be developed based on nitrilimines and 1,2,4-triaz,ine chemistry. Secondly, both novel and established energetic materials will be prepared via the direct oxidation of amines to nitro, groups using superoxides as an alternative to traditional nitration methods. The proposed research will result in both new energeti,c molecules and new enabling strategies in energetic materials chemistry which will allow the Navy to transition synthetic strategie,s developed in ourresearch group to those working in the Navy labs, and the new energetic materials prepared will be pushing the lim,its of energetic performance while simultaneously being of low sensitivity.
