试用冠醚作为气相色谱固定液文献中曾有报道,但未述及有关极性常数的测定,也未见有与其他固定液进行比较,因而无法确认所试冠醚作为固定液存在的真正必要性。本文首次报道常用冠醚—苯并-15-冠-5作为气相色谱固定液的研究结果。测定了苯并-15-冠-5的极性常数和热重稳定性,并将测定结果与其他固定液进行比较。认为苯并-15-冠-5是一种比双(2-甲氧乙基)己二酸酯更好的固定液。 Trial Crown ethers have been reported in the literature as gas chromatographic fixatives, but the determination of polar constants has not been described, and no comparison with other fixatives has been found, and it is not possible to confirm the genuine necessity of the presence of crown ether as a fixative Sex. This is the first report of commonly used crown ether - benzo-15-crown-5 as a stationary phase gas chromatography results. The polarity constants and thermogravimetric stability of benzo-15-crown-5 were measured and the results were compared with those of other fixatives. Benzo-15-crown-5 is considered to be a better fixative than bis (2-methoxyethyl) adipate.
