摘　　要：通过直接向稀释的黏土悬浮液中加入Fe-Al交联剂制备了不同物质的量比的铁铝交联黏土催化剂。研究了该催化剂在苯/H2O2直接羟基化制备苯酚反应中的催化性能。结果表明,铁铝交联黏土催化剂在苯直接羟基化反应中具有良好的催化活性,苯酚收率最高可达4.9%,选择性可高达73.5%。运用XRD、FT-IR、TG-DSC、SEM等手段对铁铝交联黏土催化剂进行了表征。The differen molar ratios of iron/aluminum pillared clay catalyst were prepared by direct introduction of Fe-Al pillaring agent into the dilute clay suspension.The result showed that Fe-Al pillared clay catalysts for the direct hydroxylation of benzene exhibited high catalytic activity.The Selectivity of phenol was 4.9% with a selectivity as high as 73.5%.Fe-Al pillared clay catalysts were characterized by XRD,FT-IR,TG-DSC and SEM.Catalytic performance was investigated for direct hydroxylation of benzene to phenol with H2O2.
