采用全氟酰氟为催化剂,三聚氰氯与氟化钾在二乙二醇二甲醚中于80℃反应,可制得三聚氰氟,产率为80～90％。当等克分子三聚氰氟与六氟丙烯在氟化钾催化下,室温反应18小时,即可得一、二全氟烷基取代产物。全氟正丙基乙烯基醚可以参与类似反应,但要困难得多。当等克分子全氟正丙基乙烯基醚与三聚氰氟在100℃反应13.5小时,大部分回收,只得少量的一取代产物。三嗪环上的全氟烷基及氟原子易被醇钠进攻。应用碱性较弱的碳酸钙或氟化钾作为酸的受体,可使三嗪环上的氟为甲氧基所取代,而保留全氟烷基。
Using perfluoroacyl fluoride as catalyst, cyanuric chloride and potassium fluoride in diethylene glycol dimethyl ether at 80 ° C can be obtained cyanuric fluoride, the yield was 80-90%. When the other molecular cyanuric fluoride and hexafluoropropylene in potassium fluoride catalyst, the reaction at room temperature for 18 hours, you can get one, two perfluoroalkyl substituted products. Perfluoro-n-propyl vinyl ether can participate in a similar reaction, but much more difficult. When the same molecule of perfluoro-n-propyl vinyl ether and cyanuric fluoride reaction at 100 ℃ 13.5 hours, most of the recovery, only a small amount of a monosubstituted product. Perfluoroalkyl and fluorine atoms on the triazine ring are easily attacked by sodium alkoxide. The use of less basic calcium carbonate or potassium fluoride as the acid acceptor allows the triazine ring to be replaced by a methoxy group while the perfluoroalkyl group remains.
