文摘:評述了近年來手性金屬配合物催化的前手性羰基化合物的不對稱硅氫化反應研究進展。The absorption is ascribe to physical absorption. silane combines with h of hydroxyl on surface of sericite, the absorption is ascribe to chemical absorption. in silane and stearic acid cooperation modification, c = o absorption peak appears in spectrum and the regional vibration of si - o - si becomes wide, which shows the physical absorption of stearic acid and chemical absorption of silane produce an effect on surface of sericite
採用紅外光譜對絹雲母改性機理進行分析,結果表明,硬脂酸改性絹雲母吸附強度較弱,容易脫附,以物理吸附為主;硅烷改性絹雲母,與絹雲母表面的羥基形成氫鍵,以化學吸附為主;硅烷與硬脂酸復合改性,其光譜中出現了c = o鍵特徵吸收峰,並且si ? o 、 si ? o ? si振動吸收區變寬表明復合偶聯劑在絹雲母表面既有硬脂酸的物理吸附,又有硅烷的化學吸附。分享友人
