Abstract:

This program was a Phase II Small Business Technology Transfer Program STTR contract with the Air Force Office of Scientific Research Contract FA9550-07-C-0105. It was carried out by Science Technology Applications, LLC as the Small Business and the University of Southern California as the Academic Institution. The goal of this proposal was the identification, synthesis and characterization of novel compounds which can serve as a nontoxic replacement for ammonium perchlorate AP. The program has been highly successful. Two promising target compounds, the ammonium salts of the tetranitroborate and the tetrakis 3,5-dinitro-1,2,4-triazoIylborate anion, BDNT4-, were identified as excellent candidates for replacing AP. Umpolung reactions were studied as a possible synthetic route towards the tetranitroborate anion, several suitable BNX4- skeletons were synthesized and characterized. The most impressive progress was made in the area of BDNT4- chemistry. The BDNT4- anion was successfully synthesized and characterized. It has good thermal stability, is hydrolytically stable, is insensitive, and the predicted performance of its ammonium salt is slightly higher than that of AP.
