Abstract
1,1-Diamino-2,2-dinitroethene (DADNE, FOX-7) is a novel explosive with low sensitivity and high performance. The unique combination of the valuable properties is a result of the structure of the compound. The molecular packing of DADNE consists of layers with strong intermolecular hydrogen bonds which stabilize the molecule. In the paper, the results of research the purity of DADNE in different recrystallization conditions and some intermediate products of its synthesis were presented. High performance liquid chromatography (HPLC) method based on the porous graphitic carbon (PGC) column packing material has been developed. Two variants of mobile phases in different pH values: acetonitrile–water and methanol–water with ammonia (NH 3) and with trifluoroacetic acid (TFA) were used. The probable mechanism of interaction between the analyte, the stationary phase, and the mobile phase was suggested.
