双羧基冠醚玻璃空心柱的研制及分离机理的研究

Preparation and Separated Mechanism of Glass Capillary Column with Dicarboxyl Crown Ether Stationary Phase

提出一种制备双羧基冠醚玻璃空心柱的新方法,对其色谱特性研究表明:用该法研制的双羧基冠醚空心柱色谱性能良好,对某些极性位置异构体的分离有特殊的选择性,还探讨了反应机理及影响分离的各种因素。

The present paper covers a new method for the preparation of glass capillary columns with dicarboxyl crown ether stationary phase and their chromatographic characteristics, including column efficiency, phase transition temperature, thermal stability, polarity and selectivity. It is shown that they have good chromatographic characteristics and unique selectivity in the separation of some polar position isomers. The reaction mechanism and the factors which affect the separated mechanism are discussed.
