Process Development, Crystallization Studies and Technology Transfer to NAVAIR, China Lake, of ADNTB
Abstract
A research and technology transfer program is proposed at the request of Dr. Daniel Tam of ONR in response to the Broad Agency Announcement, N00014-17-S-B001. The proposal was written by Profs. Karl Christe and Ralf Haiges of the Loker Research Institute and Department of Chemistry, University of Southern California, Los Angeles. The University of Southern California proposes to carry out a best effort contract for process development and crystallization studies of ammonium tetrakis(dinitrotriazolyl) borate (ADNTB). The effort will be part of an overall program to transfer the USC developed technology for a high-performing, green replacement for presently used toxic ammonium perchlorate (AP) to NAVAIR, China Lake. The ADNTB technology was developed at USC under ONR sponsorship and has been protected by US Patent 9,309,266 B2 (April 12, 2016). The effort at NAVAIR will be carried out by Drs. Mark Mason and Kenny Young, in close collaboration with USC. The proposed USC effort under this program includes the following technical approaches: 1. Investigate the preparation of HDNT by the oxidation of DAT with H2O2 or dimethyldioxirane. 2. Investigate and optimize the one-pot synthesis of HDNT from hydrazine hydrate and 2-cyanoguanidine using either H2O2 or dimethyldioxirane as the oxidizer. 3. Optimize the one-step preparation of NH4[B(DNT)4] from NH3·BH3 and HDNT in methanol solution. 4. Obtain a crystal structure of the [B(DNT)4]- anion by crystallization of the pure salt or with the help of the crystalline sponge technique using a MOF crystal. The outcome of this research is anticipated to facilitate the technology transfer of a highly promising novel High Energy Density Material (HEDM) from an academic institution to a Navy Laboratory and provide the Navy with a less toxic, environmentally more benign and affordable, high-performing energetic replacement for AP without a sacrifice in performance, thus rendering ships less vulnerable to enemy attacks and accidents. Progress in these areas will have a strong impact on Navy and DoD capabilities.
