In this work, oligomer cyanuric acid was synthesized by reaction of cyanuric acid and dichloroethane with triethanolamine as catalyst in DMF. Some factors that influenced the yield of oligomer cyanuric acid was explored by orthogonal pilot. The results indicated that, when molar ratio of cyanuric acid and dichloroethane was 1.0∶2.0, the mass ratio of Cyanuric atid and trie thylamine was 1.0∶1.5, the mass ration of cyanuric acid,DMF was 1.0∶6.0,and the reaction time was 4.0 h, the reaction could reach its optimum synthesized conditions. This work presents a way to synthesize oligomer cyanuric acid.
