| Abstract: | Carbosilane dendrimer with allyl end groups is bonded to silieagel. Reactions between the dendrimers and acid-processed silicagel take place with toluene reflux and organic base as catalyst. The chemically modified silicagel is packed into LC column and its separation characters are evaluated. Dendrimer-bonded 5ilieagel is effective Io separate homologous compounds of alcohol, alkyl-substituted benzene, metacrylic acid esters. This experiment can be designed as a comprehensive experiment for the courses of synthesis method, composite materials, analytical chemistry. |
