摘　　要：现阶段已经发现多种类型催化剂可以催化制备苯甲醛缩乙二醇,它是一种非常重要的精细化工中间体,被广泛应用于化工、医药等研究领域。以酸化凹凸棒石为初始原材料,采用浸渍法制备了负载硫酸高铈凹凸棒石催化剂Ce(SO4)2/ATP,并利用比表面积和孔隙度分析仪、傅里叶红外光谱等技术手段对催化剂进行了表征,同时考察了该催化剂催化制备苯甲醛缩乙二醇的性能。结果表明:在催化剂的用量为0.2 g、反应时间为3 h、重复次数为2次、反应物摩尔比为1∶2时的催化效率最高。It has been discovered that many types of catalysts can be used in the preparation of benzaldehyde ethylene acetal. It is a very important fine chemical intermediate and is widely used in chemical, pharmaceutical and other fields. Using acidized attapulgite as raw material, Ce(SO4)2 immobilized attapulgite Ce(SO4)2/ATP was synthesized by incipient wetness impregnation method. The Ce(SO4)2/ATP material was characterized by BET, IR and other analysis technologies, and the performance of the catalyst in the preparation of benzaldehyde ethylene acetal was investigated. The results showed that Ce(SO4)2/ATP had the highest catalytic efficiency for the preparation of benzaldehyde glycol under the conditions of dosage 0.2 g, time 3 h, reusing number 2 times, molar ratio of reactants 1∶2.
