主链杯芳冠醚聚硅氧烷固定相的研究

Study on calixcrown polysiloxane stationary phase

合成了一种杯芳冠醚单元位于聚硅氧烷主链的新型毛细管气相色谱固定相 (M -C[4 ]C - 5PSO)。该固定相具有很好的热稳定性 ,并对酚类、硝基及氯取代类芳香族位置异构体有良好的分离。

A new calixcrow polysiloxane gas stationary phase(M-C[4]C-5Pso in which calixcrown monomers lie in the main of polysiloxane was synthesized. The calixcrown polysiloxane exhibits high thermostabitity and good separation abilities for nitro, chloro-and methyl substituted benzene or phend isomers.
