Study on McReynolds Constants of Eight Crown Ether Stationary Phases

冠醚在气相色谱分析中的应用研究已有论文发表。本文测定了八种冠醚固定液的McReynolds常数,并讨论了它们的色谱性质。 1 实验 1.1 主要仪器与试剂 103气相色谱仪,上海分析仪器厂,φ4×1 000 mm不锈钢柱;电子秒表(±0.01 s);Chromosorb G-AW-DMCS(60～80目,美国);正构烷烃,

In this paper; the chromatographic characterization of eight crown ether stationary phases is relatively and comprehensively discussed through the determination of their McReynolds constants and in comparison with typical stationary phases. The reason for having different McReynolds constants for the crown ethers is attributed to the differences of their structures. Special uses for some crown ethers are introduced. The accuracies of the constants were tested and verified.
