Abstract:
PURPOSE: The polyacylhexaazaisowurtzitane(AIW) derivatives, their production method and a method for producing hexanitro hexaazaisowurtzitane(HNIW) using the same are provided, thereby HNIW can be effectively produced in higher yield by using AIW easily produced. CONSTITUTION: The polyacylhexaazaisowurtzitane(AIW; polyacyl-2,4,6,8,10,12- hexaaza-tetracyclo £5.5.0.0(5.9).0(3.11)|dodecane) derivatives represented by the formula (I), in which X is RCO, wherein R is H or C1 to C10 alkyl, X' is H or R'CO, wherein R' is H or C1 to C10 alkyl, X'' is H or R''CO, wherein R'' is H or C1 to C10, and R, R' and R'' are the same or different, is produced by reacting hexaarylmethylhexaazaisowurtzitane(HArlW) with (R1CO)2O in the presence of metal catalyst, H2 and organic solvent; removing the solvent; and mixing the remnant with (R1CO)2O, (R2CO)2O, R2COX or R2COOH. The HNIW is produced by reacting AIW derivatives and their isomers with nitrogenating agents such as (R1CO)2O, (R2CO)2O, R2COX or R2COOH.

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. Especially, the energy content of the plasticizer of the present invention is heightened by minimizing the content of the diformal generated as a side product, so that it is favorably adapted for use in an insensitive high performance explosive and a propellant.

Abstract:
PURPOSE: An energetic nitro-formal plasticizer for explosive formulations comprises eutectic mixture mixed with bis(2,2-dinitropropyl)formal(BDNPF), 2,2-dinitropropyl 2,2-dibutyl formal(DNPBF) and bis(2,2-dinitrobutyl)formal(BDNPF). The energetic nitro-formal plasticizer exhibits superior thermal/chemical properties with less production cost. CONSTITUTION: The molecular ratio of BDNPF/DNPBF/BDNPF in formulation of this plasticizer is in the range 20-68%/28-50%/4-30%. The plasticizer is allowed to contain diformal, however its content is desirable controlled to be not more than 3%. The preparation method of this plasticizer comprises the steps of (i) dissolving 2,2-dinitropropanol and 2,2-dinitrobutanol in the mole ratio of 3 to 6:1 at 0 to 30deg.C in an organic solvent like methylene chloride; (ii) at 20deg.C or lower, adding sulfuric acid solution in which formaldehyde sources such as paraformaldehyde and s-trioxane is dissolved; (iii) refining obtained mixture.
