(319a) Formation of Low Acidity Adnbf by Reactive Crystallization

ADNBF has been extensively studied as a promising energetic material because this compound has some desirable properties such as good thermal stability and low impact insensitivity. However, acidity level of ADNBF synthesized from acetic acid, which is usually taken as a reactive medium, was measured to be higher than that of general regulation of explosives such as TNT, RDX, and HMX. Inclusion of acetic acid during precipitation of ADNBF crystals was found to be a major reason for high acidity of synthesized ADNBF. Acidity level of explosives is very important for long term stability of final products and therefore should be controlled during synthesis or by recrystallization. Here we present primary results on reactive crystallization of ADNBF from various solvents for the control of acidity level and crystal morphology.
