Based AHDNE Organic Amine Synthesis And Properties Of Energy-containing Complexes

Energetic materials is a kind of special materials, which contain many explosives, oxidizing and flammable groups, and release a lot of heat or gas when react. These materials are mainly used for national defense construction.1,1-Diamino-2,2-dinitroethylene (FOX-7) has good thermal stability and good safety performance, and belongs to a new type of energy-insensitive energetic materials, It can be compatible with many materials, and exhibit excellent properties. FOX-7has been studied by our group for many years.In our laboratory, AHDNE was synthesized, AHDNE is a new energetic materials. It has the same characteristics to FOX-7and also has a highly active adjacent amino-hydrazino group, which can react with many compounds to form new substances. In this paper, K(AHDNE) was synthesized through the reaction of AHDNE and KOH in methanol solution, however a new compound was also synthesized in the above solution (2,3-dihydro-4-nitro-3-(dinitromethylene)-1H-pyrazol-5-amine), where two AHNDE-anion became a2,3-dihydro-4-nitro-3-(dinitromethylene)-1H-pyrazol-5-amine anion (NNMPA) with the losing of hydrazino group. Ag(AHDNE), Pb(AHDNE)2, Ni(AHDNE)2·2H2O were synthesized by KAHDNE and AgNO3, Pb(NO3)2, Ni(NO3)2, and the compounds of [Cu(NH3)4](DNANT)2,[Cu(en)2](DNANT)2and [Ni(NH3)6](DNANT)2were synthesized by Cu(NO3)2、Ni(NO3)2in an organic amine. The compound of [Ni(phen)3](AHDNE)2(CH3CH2OH)-4H2O was synthesized by Ni(NO3)2and Phenanthroline in the solution of ethanol at85℃. Meanwhile, five single crystals were determined by X-ray diffractometer.K(NNMPA):Monoclinic; P2i/C;[Cu(NH3)4](DNANT)2:Triclinic; P-i;[Cu(en)2](DNANT)2:Monoclinic; P2i/C;[Ni(NH3)6](DNANT)2:Monoclinic; P2i/C;[Ni(phen)3](AHDNE)2(CH3CH2OH)-4H2O:Triclinic; P-1The thermal behaviors of the above compounds were studied by DSC and TG/DTG methods. Thermal decomposition kinetic equation of K(NNMPA),[Cu(NH3)4](DNANT)2,[Cu(en)2](DNANT)2, Cu(bipy)(AHDNE)2, Ag(AHDNE), Pb(AHDNE)2, Ni(AHDNE)2-2H2O were obtained under the non-isothermal conditions. The continuous specific heat capacities of seven compounds were determined by Micro-DSC III instrument. Based on the Cp equation, the molar heat capacities of the above compounds were calculated at298.15K. Meanwhile, using Cp functions and thermal decomposition parameters, the adiabatic times-to-explosion was estimated. At last impact sensitivity was tested, as an important factor, which can be used to estimate the safety of energetic materials. Experimental results show that:the specific heat capacity of K(NNMPA),[Cu(NH3)4](DNANT)2,[Cu(en)2](DNANT)2, Ag(AHDNE) are289.9,512.6,543.55, and219.46J-mol-1·k-1, respectively. The adiabatic times-to-explosion of (K(NNMPA),[Cu(NH3)4](DNANT)2and [Cu(en)2](DNANT)2are42.3,137.76, and84.40s, respectively. The impact sensitivity of K(NNMPA),[Cu(NH3)4](DNANT)2[Cu(en)2](DNANT)2, Cu(bipy)(AHDNE)2, Ag(AHDNE)、Pb(AHDNE)2and Ni(AHDNE)2>2H2O are16.7,6.9,18.6,24,4.5,10.5, and5.01J, respectively. Meanwhile, their change rule was discussed.
