【摘要】 制备了八苯基八硅倍半氧烷的五硝基和六硝基化合物以及五硝基化合物的聚合物。它们用作气相色谱固定相,极性较强、热稳定性可达280℃。添加适当减尾剂,可分离某些极性化合物的混合物。更多还原

【Abstract】 The nitro-phenylsilsesquioxane with five and six nitro groups andpolymer with five nitro groups were prepared by nitration.These sub-stances can be used as the stationary phases for gas chromatographicseparation of the mixture of polar compounds,when a suitable modi-fier was operated in order to reduce the tailing phenomena.Thermalstability of the nitro-phenylsilsesquioxane and its polymer with fiveor six nitro groups was 280℃.更多还原
