| 本文通过比较多条制备苯并三嗪的途径，确定采用操作条件温和，收率较高，原料易得，后处理容易。以邻硝基苯胺为起始原料，采用氨基氰和浓盐酸进行热反应, 而后用碱使其闭环生成反应3-氨基-1,2,4-苯并三嗪-1-氧化物，再氧化的工艺路线。合成的产物经确认，为目标产物。 |

| In this paper, we compared several pathways used to synthesis phentriazine and determined to choose the following route to synthesis phentriazine for its mild reaction conditions,higher yield, easy availability of raw materials and the simple post treatment: use o-nitroaniline as the starting material, add cyanamide and concentrated hydrochloric acid to let the exothermic reaction go, after that the cyclization reaction which obtained the 3- amino-1,2,4-benzo triazine-1-oxide were performed by adding alkali , the last step—oxidation. The synthesised compound was confirmed to be the target product. |
