【摘要】 <正> 冠醚是一类新型的有机化合物。由于具有选择性络合金属离子的性能、增溶性能和在非极性溶剂及亲脂膜中的传递性能,这类化合物已被广泛的应用于金属元素的络合分离、有机合成、环境化学、仿生化学以及医药、农药化学等方面。对于冠醚的分析,文献中报导得很少。Egorova等曾用气相色谱法测定冠醚中的杂质。我们曾用气相色谱法对冠醚反应液进行过分析本文用国产SP-2305E型气相色谱仪,更多还原

【Abstract】 A rapid gas-liquid chromatographic method has been developed and applied to the analysis of benzo-15-crown-5 in reaction mixture.Crown ether samples were separated at 284℃ on a column(200×0.4 cm) of 15% E-301 on silanized white support 102 with hydrogen flame ionization detection.Dibutyl phthalate was used as an internal standard.The title compound was quantified by using a calibration curve.更多还原
