Preparation of Magnetic SO_4~（2-）/ZrO_2/Fe_3O_4/Palygorskite Solid Acid Catalyst and its Catalytic Properties
摘要
Abstract
SO42-/ZrO2/Fe3O4/palygorskite solid acid catalysts were prepared using palygorskite as a support via a coprecipitation method.The catalysts were characterized by X-ray diffraction,transmission electron microscopy,energy dispersive X-ray spectros-copy and superconductivity quantum interference device,respectively,to investigate the catalysis of butyl acetate synthesis.The ef-fects of Fe3O4,ZrO2,and calcination temperature on the catalytic properties of the catalyst were also investigated.The results show that the catalyst exhibits a higher catalytic activity and the more intensive magnetic characterization,and the esterification rate is 89.26%.The addition of Fe3O4 could improve the activity of catalyst and facilitate the separation and recovery of the catalyst.The esterification rate could still be 74.53% after used for four times.关键词
