摘　　要：研究了常规浸渍法和泥浆浸渍法制备不同Mo负载量的MoO3/SiO2催化剂对草酸二甲酯(DMO)与苯酚酯交换反应的催化活性的影响。泥浆浸渍法制备的MoO3/SiO2催化剂比常规浸渍法制备的表现出更高的反应活性和分散性能。且泥浆浸渍法无需高温焙烧,减少了能耗,也没有废液和含氮气体的生成,是一种新型环保的制备负载型催化剂方法。The effect of Mo loadings and preparation methods,slurry and conventional impregnation,on the performances of MoO3/SiO2 catalysts in transesterification of dimethyl oxalate（DMO） with phenol was investigated.Slurry prepared MoO3/SiO2 catalyst exhibited higher activity and dispersion capacity than conventional one.Slurry MoO3/water was used instead of an ammonium heptamolybdate solution.Highly dispersed amorphous Mo catalysts were obtained,closely to the catalytic activity without calcinations,waste solutions,and calcining nitrogenous gases.
