Abstract: Disclosed are glycidyl di-nitropropyl carbonate and poly(glycidyl di-nitropropyl carbonate) which is prepolymer used as an energetic binder for an insensitive and high performance explosive. The present invention introduces the nitro group instead of the nitrate group, thereby enabling to provide the prepolymer having the high thermal stability (thermal decomposition initiating temperature of at least 200° C. or higher) more excellent than that of the conventional energy binder.

Abstract: An energetic plascitizer comprising bis(2,2-dinitropropyl) formal, 2,2-dinitropropyl 2,2-dinitrobutyl formal and bis 2,2-dinitrobutyl) formal in a molar ratio of 20˜68%/28˜50%/4˜30% is, described. It is also provided a method for synthesizing the plasticizer comprising: dissolving 2,2-dinitropropanol and 2,2-dinitrobutanol into an organic solvent to form an organic solution, in which the molar ratio of 2,2-dinitropropanol to 2,2-dinitrobutanol is 3:1-6:1; adding to the organic solution a sulfuric acid solution where formaldehyde source was dissolved, wherein the temperature of reaction medium is maintained below 20° C.; and separating and purifying the product from the reaction mixture. The plascitizer according to the present invention has an excellent thermal and chemical properties while incurring a low production cost.

Abstract: 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.

Abstract: A preparation method of 3-nitro-1,2,4-triazol-5-one using 1,2,4-triazol-5-one (TO) and mixed acid through a stable nitration process which can minimize a large exotherm and associated frothing problem during crystallization by inducing a crystal nucleus to be generated at a low temperature of 35° C.-45° C.
