以三聚氯氰(CYC)、二乙醇胺(DEA)和伯胺为反应剂,分步考察碱催化剂、反应时间等对胺亲核取代嗪氯反应结果的影响,并在此基础上合成了一系列的多元羟烷胺基-1,3,5-三嗪(3a,3b,3c),其结构均经元素分析、FTIR、1H NMR和ESI-MS表征。结果表明,CYC第一、二、三氯的取代反应,宜分别选二乙醇胺、三乙胺和碳酸氢钠作碱催化剂,并依次在-1~5℃、45~50℃和85~90℃下反应2 h、7 h和16 h;所得多元羟烷胺基-1,3,5-三嗪具有双亲性.
Cyanuric chloride (CYC), diethanolamine (DEA) and primary amine as reactants, step by step to investigate the base catalyst, the reaction time on the nucleophilic substitution of amine chlorine reaction results, and on this basis, a The series of polyhydroxyalkylamino-1,3,5-triazines (3a, 3b, 3c) were characterized by elemental analysis, FTIR, 1H NMR and ESI-MS. The results showed that the first, second and trichlorine substitution reaction of CYC, respectively, should be selected diethanolamine, triethylamine and sodium bicarbonate as base catalyst, followed by -1 ~ 5 ℃, 45 ~ 50 ℃ and 85 ~ 90 ℃ Under the reaction 2 h, 7 h and 16 h; resulting polyhydroxyalkylamino-1,3,5-triazine has amphipathic.
