介绍了一种用二羟基取代饱和漆酚冠醚固定相交联玻璃毛细管柱的新方法。通过测定柱效、相变温度、热稳定性和极性对柱子进行了评价。结果表明，它们在分离酚类、硝基化合物和单糖方面具有良好的层析特性和独特的选择性。这些柱子的平均极性与SE-52和FFAP相当。并对分离机理进行了探讨。
A new way of cross-linking glass capillary columns with dihydroxy-substituted saturated urushiol crown ether stationary phase is described. The columns were evaluated by determining the column efficiency, phase transition temperature, thermal stability and polarity. It was shown that they have good chromatographic characteristics and unique selectivity in separating phenols, nitro compounds and monsaccharides. The average polarity of these columns was comparable to those of SE-52 and FFAP. The mechanism of separation is discussed.
