端烯丙基冠醚的合成

Synthesis of Assylerown Ethers

从邻苯二酚出发合成了两种未见文献报道的环上含有端烯丙基的冠醚化合物。这两种冠醚的结构均经元素分析、ＩＲ、￣１ＨＮＭＲ和ＭＳ所证实。两种冠醚分别与有机硅化合物聚合制备的气相色谱固定相，在分离酚类和二硝基甲苯类异构体方面具有极好的选择性。

Two crown ethers, ADB16-C-5 and ADTB 16-C-5 were synthesized, Their structurewere confirmed by elemental analysis, IR,￣1HNMR and MS. Crown ether 5 and 6 subetitutedpolysiloxane were used as capillary gas chromatographic stationary phases,which have excellent selec-tivIty for the separtion of polar position isomers, especially for phenol and dinitrotoluene isomers.
