摘　　要：以CTAB为模板剂,通过溶胶-凝胶法制备了介孔二氧化硅,将聚(苯乙烯-二乙烯苯)包覆在介孔二氧化硅表面,并进行磺酸化制备了一种新型的固体酸催化剂;通过FT-IR、TGA、TEM等表征方法对合成的磺酸化介孔二氧化硅进行了表征.结果表明:表面聚合物基团和磺酸根基团成功地引入到了二氧化硅表面,磺酸化的介孔二氧化硅具有较好的孔道有序结构.磺酸化介孔二氧化硅对苯甲醛和乙二醇的加成反应表现出了较高的酸催化性能.The mesoporous silica was synthesized by sol-gel method using CTAB as template,and then a novel ordered mesoporous solid acid catalyst was prepared by sulfonation of polymers coating on surface of mesoporous silica.The samples were characterized by FT-IR,TGA and TEM.The results indicated that the meso-structure of the sample was retained,and the polymer groups and —SO3H groups had been successfully incorporated on the surface of silica.The sample show high catalytic performance toward the addition reaction of benzaldehyde and ethylene glycol.
