The title compound, a polynitro carboxylic ester was synthesized starting with bis(2,2,2 trinitroethyl) formal via a 3 step reaction:denitration, Henry reaction and esterifiction. The structure of the obtained ester was identified by mp, IR, 1 HNMR,MS and elemental analysis. After experiencing a quite number of runs, the synthetic procedure has been improved and discussed. In addition, some important performances of the target compound were measured and are as follows: density 1.57g/cm 3 (suspension method), sensitivity to impact (explosion probability) 0%(drop hammer of 10kg,drop height of 250mm, 25 runs, charge 50±1mg), endothermic peak temperature of thermal decompersition 266.3℃(DTA method).
