| 摘要 |
The present invention provides an energetic plasticizer comprising bis(2,2-dinitropropyl) formal and a material that keeps bis(2,2-dinitropropyl) formal from crystallizing out, wherein the material that keeps bis(2,2-dinitropropyl) formal from crystallizing out is bis(2,2-dinitropropyl) diformal. In case where BDNPDF is used to prevent BDNPF from crystallizing out, BDNPF is not crystallized even though it stands at the temperature -20° C. for more than 6 months, while its thermal and chemical properties are similar to that of conventional plasticizers. Also, by using BDNPDF, that has been considered as a unfavorable side product, as an inhibitor of crystallization, no additional process is required to remove BDNPDF. Moreover, the cost involved is lower.
