蒙脱石/聚苯胺复合材料的制备及其催化Knoevenagel缩合反应研究

Synthesis and Catalytic Knoevenagel condensation reaction of Montmorillonite/polyaniline Composites

将苯胺在酸性条件下在蒙脱石的层间进行原位聚合,制备得到蒙脱石/聚苯胺复合材料,将此复合材料用稀的氢氧化钠溶液进行洗涤即得到具有弱碱性的复合材料,此复合材料对苯甲醛与丙二腈的Knoevenagel缩合反应具有良好的碱催化效果。

Montmorillonite/Polyaniline composite materials was prepared when aniline was polymerized in situ between the nanosheets of montmofillonite in acidic medium,this composite materials became a good solid base after it was rinsed by di- lute sodium hydroxide solution. This solid base has perfect catalytic performance for knoevenagel condesation reaction of aro- matic aldehyde with malononitrile.
