Polynitropyridines compounds is an important energetic materials . In this thesis, by oxidation , nitration , phenylephrine , reduction unit was synthesized 4 - amino-3 ,5 - dinitropyridine and 4 - amino-3 ,5 - two nitro-2 - pyridone for further synthesis of nitropyridine insensitive explosive 2,4,6 - amino-3 ,5 - dinitro- pyridine -N-oxide to provide intermediates. Reaction mechanism combined with each unit to discuss the material ratio, reaction time , temperature and other factors on the yield obtained optimum conditions . Of 4 - aminopyridine Preparation of 4 - amino-3 ,5 - dinitro- pyridine optimum conditions : fuming nitric acid and sulfuric acid volume ratio of 1:4 , 1.3:1 nitrate , nitro- , room temperature , temperature dinitration 85 ℃, 63% yield ; with 4 - amino-3 ,5 - dinitropyridine as raw material by hydrogen peroxide oxidation synthesis of 4 - amino-3 ,5 - two nitro-2 - pyridone optimum conditions : the reaction at room temperature , H 2 O 2 with a 4 - amino-3 ,5 - dinitro 7.5:1 molar ratio of pyridine , acetic acid and the volume ratio of hydrogen peroxide 4.5:1 , yield 61%. With IR, HNMR, GC-MS, LC-MS and other analytical testing methods were used to characterize the target .
