最近在读一篇paper,是有关於chemisy of silica surface的 这是第一段Introduction的内容: Derivatization and modification of the silica surface are enormously important in both pure and applied chemistry. In addition to the popular silylation reactions that facilitate the formation of useful composites and generate a variety of useful “phases” for chromatography,silica-surface modification is extremely useful for “immobilizing” moieties with catalytic activity. 我有几个问题: 1)silylation是什麽? 2)silica surface又是如合进行催化反应? ps:我有试者找过reference,但是是1986 or 1988年的书学校找不到 再来里面有一张很重要的NMR图谱 是用13-C,29-Si,及27-Al去测它的sample 我有学过1-H的NMR,13-C的只会一点点 而29-Si跟27-Al就完全没学过了 所以... 3) 可否大概讲解一下怎麽看29-Si及27-Al的NMR? 以上.......请各位高手解答 十分感谢您的的回应!! --
