摘　　要：本文对三聚氯氰与苯胺-2,5-双磺酸发生一次缩合作了介绍,对该一缩物与乙二胺进行二次缩合反应的工艺进行了研究。研究结果表明,调节缩合pH 6.5~7.0,采用微通道工艺可以大幅度提高反应效果,二缩物含量可提高到85%以上。The condensation between cyanuric chloride and aniline-2,5-disulfonic acid was introduced,and a first condensation compound(F-CC)was obtained.The second condensation between F-CC and ethylenediamine was discussed.The results showed that:in a micro reactor,when the condition of pH 6.5~7.0,the content of the second condensation compound(S-CC)raised to 85%.
