| Summary: | The synthesis of 1-propyl-2-nitroguanidine (PrNQ) was performed, according to an originally
modified procedure, and ca. 160 g of PrNQ was obtained in a single run. The purity of it is sufficient
for further research. The structure of PrNQ molecule has been confirmed by using nuclear magnetic
resonance spectrometry (NMR). The melting (99°C) and decomposition (200°C) points were determined
by using differential scanning calorimetry (DSC) at a heating rate of 1°C/min. Mechanical sensitivity
tests showed that PrNQ is an nergetic material with impact sensitivity similar to the sensitivity of one
of the least-sensitive explosives, i.e., 1,3,5-triamino-2,4,6-trinitrobenzene (TATB). It has been shown
that PrNQ can be elaborated by cold pressing or melt-cast technique.
