Preparation and characterization of nano N,N'-bis(1,2,4-triazol-3-yl-) -4,4'-diamino-2,2', 3,3', 5,5', 6,6'-octanitroazo-benzene explosive

摘要

In this study, nano N,N'-Bis(1,2,4-triazol-3-yl-)-4,4'-diamino-2,2', 3,3', 5,5', 6,6'-octanitroazo-benzene (BTDAONAB) is prepared by spraying a solution of BTDAONAB–acetone into n-hexane or carbon tetrachloride during solvent/anti-solvent process. For this process, suitable solvent and anti-solvent have been chosen. A combination of a supersaturated solution of soluble material and an anti-solvent provides a driving force for the preparation of nanoparticles. During mixing process, the rate of nucleation is relying on saturated solvent. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), thermogravimetry (TG) and differential thermal analysis (DTA) analysis methods are used to characterize nanoparticles.
