摘　　要：An experimental study was carried out on the direct nitration of 1,4,5,8-tetraaza-bicyclo-[4,4,0]-decane to synthesize 1,4,5,8-tetranitro-l,4,5,8-tetraazabicyclo-[4,4,0]-decane （TNAD） with N205 catalyzed by acidic ionic liquids. Various ionic liquids, such as [HMim]X, [（CH2）4SO3HMim]X and [Capl]X （X =pTSO-, NO3 , HS04-）, and various parameters such as equivalents of ionic liquid, molar ratio of N205 tO the starting material, reaction time and temperature, and solvent were investigated, Ionic liquid [（CH2）4SO3HMim]HS04 showed better catalytic activity. In the presence of 3% molar ratio of [（CH2）4SO3HMim]HS04 ionic liquid to the staring material, the yield of 1,4,5,8-tetranitro-l,4,5,8- tetraazabicvclo-14.4.01-decane was improved bv 6.2~; comnared to the system without ionic liauid.An experimental study was carried out on the direct nitration of 1,4,5,8-tetraaza-bicyclo-[4,4,0]-decane to synthesize 1,4,5,8-tetranitro-l,4,5,8-tetraazabicyclo-[4,4,0]-decane （TNAD） with N205 catalyzed by acidic ionic liquids.
