Synthesis of Insensitive N-2,4-dinitrophenyl-N¹-nitroguanidine

A new, insensitive nitroguanidyl functionalized nitrogen-rich material derived from 2,4-dinitrophenyl derivative was synthesized. N-2,4-dinitrophenyl-N1-nitroguanidine (DNP-NQ) has a crystal density of 1.74 g/cm3. The synthesis and properties of DNP-NQ are described. DNP-NQ was characterized by nuclear magnetic resonance (NMR), infrared spectroscopy, and gas pycnometry. Thermal properties were studied by differential scanning calorimetry (DSC). Results from small-scale sensitivity tests indicate that DNP-NQ is less sensitive than Cyclotrimethylenetrinitramine (RDX). DNP-NQ can be prepared in high yield.
