摘要
以不同类型的酸性多孔沸石分子筛（ZSM-5、Beta、USY和MOR）为催化剂，在没有强碱添加剂的条件下实现N-对甲苯基丙烯酰胺和乙醇的迈克尔加成反应。利用X射线衍射、N2-物理吸附和NH3-程序升温脱附技术对沸石催化剂进行表征，并考察了不同类型的多孔沸石对反应活性和选择性的影响。结果表明，酸性多孔Beta沸石分子筛具有更好的催化活性。
Abstract
Michael addition reaction between N-p-tolyl acrylamide and ethanol is achieved over different acidic porous silicate-alumina zeolites (ZSM-5,Beta,USY and MOR) in the absence of any alkaline additives.These zeolite catalysts are characterized by X-ray diffraction,N2-physical absorption and temperature programed desorption of ammonia,and the influences of different zeolite catalysts on the reaction activity and product selectivity are investigated.Results show that acidic porous Beta zeolite has the highest catalytic activity among those.
