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.
----------
N2F4 reacts with perfluoroethylene under pressure at about 100
0C to give good yields of octafluoroethylene- diamine.[2, 3] we
repeated this work on a small scale and were able to prepare 2.Og
of octafluoroe*hylene diamine. Scale-up of this reaction to a 40-g
resulted in a serious explosion and loss of the autoclave and other
equipment required for this work.
