摘要： 四苯基苯硅氧烷聚合物固定相具有较高的热稳定性,对正构烷烃有较好的色谱分离性能,但对正构醇类则不能分离^[1]。

Abstract: The hydrolysate and prepoiymer of a mixture of dimethyldichorosilane, phenyltrichlorosilane and tetraphenylphenyltriethoxysilane were prepared. They were dissolved in benzene and then coated on the diatoma-ceous supports respectively.The coated support was heat-treated under a stream of nitrogen at 400℃ for 12 hours.The prepared column has been used at a temperature up to 270℃ without bleeding and gave a number of HETP of 1200 plates per metre. A mixture of n-alkanes containing C₇ -C₃₀could be well separated by the prepared column with the temperature programmed to 280℃. A mixture of n-alkanols containing C₄OH, C₆OH, C₈OH, C₁₀OH, C₁₂OH, C₁₄OH, C₁₆OH and C₁₈OH has been well separated also when the temperature was programmed to 250℃.n-C₁₆H₃₄ and n-C₁₀OH have been quantitatively determined by the column.The effects of the surface properties of the supports, the weight percentage of the hydrolysate or prepoiymer used in preparing the column and the temperature of heat-treament are discussed.
