用β—氯乙基缩水甘油醚均聚物分别与甲醇、乙二醇单甲醚和一缩二乙二醇单乙醚的钠盐进行反应,合成了三种侧链长短不同的线型多足聚醚。若在反应体系中添加少量三元醇化合物,则可得到交联型多足聚醚。研究了这类聚醚对K~+、Na~+的络合性能以及它们在Wolff-Kishner反应、碘代反应和二氯卡宾加成反应中作为相转移催化剂的活性。实验结果表明,这类多足聚醚是上述反应有效的相转移催化剂。交联型多足聚醚尚具有反应后易于回收和重复使用的优点。
Β-chloroethyl glycidyl ether homopolymer were respectively reacted with sodium salt of methanol, ethylene glycol monomethyl ether and diethylene glycol monoethyl ether to synthesize three kinds of linear multi-type Polyether. If a small amount of triol compound is added to the reaction system, a crosslinked multi-legged polyether can be obtained. The complex properties of these polyethers to K ~ +, Na ~ + and their activity as phase transfer catalysts in Wolff-Kishner reaction, iodination reaction and dichlorocarbene reaction were studied. The experimental results show that this type of multi-foot polyether is an effective phase-transfer catalyst for the above reaction. Cross-linked multi-foot polyether is still easy to recycle after reaction and reuse advantages.
