Hydrolytic Stability Study of Tetranitroglycoluri (TNGU) Produced via the US Army Research Laboratory's Synthetic Method.

摘要

Tetranitroglycoluril (TNGU) was prepared according to the US Army Research Laboratory s (ARL s) method by the nitration of imidazo-[4,5-d]-imidazole nitrate using trifluoroacetic anhydride and 100% nitric acid. This resulting material was then subjected to hydrolytic stability studies in which it was placed into a temperature and humidity chamber set to 23 C and 85% relative humidity and the change in concentration of TNGU was measured over time through the use of nuclear magnetic resonance spectroscopy.
