摘要
通过直接合成方法,制备了胺基功能化的HMS型有机无机杂化介孔碱性催化材料(Amx-HMS).采用粉末X射线衍射分析、透射电镜、氮气吸附-脱附、29Si固体核磁共振、红外光谱和元素分析等方法对合成材料进行了表征.通过典型的2′-羟基苯基甲基酮和苯甲醛缩合制备黄烷酮的反应对其碱催化活性中心进行了表征.
A hybrid mesoporous HMS silica materials were synthesized via co-condensation between tetraethylorthosilicate (TEOS) and bis [ 3- (trimethoxysilyl) propyl ] amine ( BTMSPA ) by using octadecylamine as the template through the "S^0I^0" route. The sequential addition of TEOS and BTMSPA resulted in well-ordered porous hybrid silicates. The synthesized materials were characterized by means of X-ray diffraction, N2 gas adsorption-desorption experiments, 29Si MAS NMR and condensation reaction of benzaldehyde with 2'-hydroxyacetopheone.
