摘要：

通过氯化和胺化等手段对有序介孔聚合物材料(FDU-16)进行功能化, 成功地将胺基引入到介孔聚合物骨架中, 制备出新型有序介孔固体碱催化材料. X射线衍射(XRD)、 氮气吸附-脱附及透射电子显微镜(TEM)表征结果表明, 功能化后的固体碱材料依然保持高度有序性; 红外表征结果表明, 大量的胺基被引入到材料的骨架中. 在Knoevenagel缩合中, 这种新型有序介孔固体碱材料表现出比功能化的介孔二氧化硅等材料更高的催化活性, 这主要归因于其具有较高的比表面积、较强的碱性以及较多的活性中心.

Abstract:

A series of amine- or diamine-functionalized mesopolymers with cubic mesostructures has been prepared by two-step chemical modification procedures involving chloromethylation and a subsequent amination reaction of the FDU-16 mesoporous resol materials. The sample was carefully investigated by various techniques such as X-ray diffraction(XRD), N2 adsorption-desorption, transmission electron microscopy(TEM) and infrared spectrometry(IR). Characterization results suggested that the mesostructure of the sample was retained during the chloromethylation and amination. The amino-group functionalized mesopolymer materials prove to be efficient heterogeneous base catalysts in Knoevenagel condensation.

Key words: Solid base catalyst, Ordered mesopolymer, Amino-group functionalization, Knoevenagel condensation
