以单硅酯(2-(环戊基-1,3二烯基)乙基)三乙氧基硅烷(TEECp)和含有亚乙基桥键的硅酯a 1,2-二(三乙氧基硅基)乙烷为硅源,以三嵌段共聚物P123为模板剂,通过调节TEECp预水解时间,采用共聚法合成了环戊二烯掺杂乙烷桥联材料(Cp-PMO),并采用小角X射线衍射.N_2物理吸附、透射电镜、红外光潜和热重等技术对样品进行了表征结果表明,环戊二烯基被成功引入到乙烷桥联材料中,所得Cp-PMO样品具有高度有序的二维六方介孔孔道,热稳定性较高;随着材料中环戊二烯含量的增加,其有序性降低,孔径、比表面积和孔体积均有所减小,孔壁逐渐增厚在乙酸乙酷与正丁醇的酷交换反应中,Cp-PMO样品表现出较高的催化活性.当该样品中环戊一烯含最为30%时,乙酸乙醋转化率和乙酸丁酯收率分别可达19.3%和10.6%.
