A New Energetic Mixed Formal Plasticizer | Chemical Reaction

The thermogravimetry (TG) analysis of the new mixed formal plasticizer shows an acceptable stability for practical applications. This new plasticizer is expected to be cheaper than the existing mixed formal because only one compound of starting material, DNP-OH, is required, DNB-OH will not be used for this process, and the yield of formalization reaction was increased from 75% to more than 90%. Energetic Polynitro Formal Plasticizers.Yet another object of this invention is to provide an improved plasticizer which has good thermal stability. These and other objects of this invention are accomplished by providing energetic plasticizers which are binary and ternary mixtures of bis2,2-dinitropropyl formal BDNPF, bis 2,2,2-trinitroethyl formal TEFO, and 2,2-dinitropropyl 2,2,2-trinitroethyl formal TNEPF.

FEFO – blastprep

Unlike several other proposed new energetic binders, FEFO has good thermal stability. The main disadvantage of FEFO is its very high toxicity, which necessitates precautions during handling. FEFO is also somewhat volatile, which, in association with the compound's toxicity, posses a hazard, and requires that any composition be sealed in teflon wrapping before use.
