Study On The Synthesis Of Glycoluril Derivatives&the Performance Of TEX

Modern weapon has more and more demanding for energetic materials especiallyexplosives in performance such as thermal stability, impact sensitivity and frictionsensitivity and so on, so a new generation of high energy density materials(HEDM) hasreceived research interests of energetic materials workers all over the world.Nitrourea energetic material has been one of the research focuses because of its highdensity and low sensitivity. In this paper, trimerglycoluril was synthesized by usingglycoluril as the starting material, then tetranitrotrimerglycoluril was prepared by directnitration of trimerglycoluril, which laid a solid foundation for fundamental performanceresearch later. Glycoluril, traditional urea class compound, has good modification.Benzylamine derivatives with multi-cycles also syntheizied through Mannich reaction andits reduction production were obtained by reduction. In order to strengthen the applicationof cucurbituril in the field of energetic materials, urease was tried to hoist the carbonyl ofcucurbituril off by using the biological method.Rigid caged compound4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo-[5.5.0.05.903,11]-dodecane(TEX) is a HEDM, joint polycycle makes caged compoundsrelease super energy, meanwhile, it has great performance on stability and sensitivity. Wealso studied the performance of TEX and developed a high performance liquidchromatography(HPLC) method for the analysis of TEX. The kinetic parameters andthermodynamic parameters of thermal decomposition of TEX were analyzed by TG-DTGand DSC, the compatibility of TEX with main components of propellants was also studiedby using DSC method. The results indicate that TEX is stable to heat and the binary systemof TEX with RDX,-Pb, NC, DINAand aluminium podwer(micron order) was compatible.Thus TEX should be applied to energetic materials such as propellants.
