Detonation Chemistry: An Investigation of Fluorine as an Oxidizing Moiety in Explosives
Abstract
This report investigated the use of fluorine in the form of the difluoramino (NF2) group as an oxidizing moiety. Bis- and tris-difluoramino perfluorobutane, previously unknown, were especially synthesized for this study. Detonation calorimetry was performed to determine the exact detonation product composition and the hast of detonation of a series of NF2 compounds and mixtures. Cylinder tests were then performed to determine their detonation performance. Similar tests on NO2 compounds were used for comparison. For reasons of toxicity and safety, remote mixing and loading apparati were designed and built for certain of the materials. Materials were chosen to highlight certain of the detonation products. Hydrogen fluoride was found to be a favorable detonation product compared with H2O, CO2 outperforms CF4 at all cylinder expansion ratios, and Al2O3 was a favorable detonation product compared to AlF3. The most important result is the better understanding of the mechanism of reaction of small-particle aluminum in a detonation.
