Abstract:

This invention relates to organic formals and more particularly to polynitro organic formals. Bis2-fluoro-2,2-dinitroethyl formal FEFO and Bis2,2-dinitropropyl formal BDNPF are used as energetic plasticizers in explosive and propellant compositions. FEFO has a high energy content but is volatile and toxic and has a relatively high melting point. BNDPF is low in energy and has an even higher melting point, requiring the use of an energy-decreasing melting point depressant. Mixtures of FEFO and BDNPF can be used to obtain a lower melting point and intermediate levels of energy and volatility, but the improvements in melting point and volatility are small at the eutectic composition of approximately 70 FEFO and 30 BDNPF.
