A variety of solid organic compounds, such as Schiff bases, azines, hydrazones, thiocarbonohydrazones, thiosemicarbazones, and hydroxy compounds, on mixing with metal powders, especially with magnesium, become synergistically hypergolic with white fuming nitric (WFNA). In the absence of magnesium powder, these compounds are either nonhypergolic or have longer ignition delays, when WFNA is used as oxidizer. The synergistic ignition behavior has been explained in terms of increased exothermicity of the system, primarily due to the heat evolving chemical reactions occurring between the fuels (organic compound and magnesium) and the oxidizer in the preignition stage.
