Abstract:
Fe3O4 nanoparticles were synthesized by hydrothermal method and the catalytic performance of dehydration was studied. The effects of the used amount of Fe3O4 nanoparticles and catalytic cycle on the yield and turnover number of diethyl malate were investigated. By changing the morphology of Fe3O4 nanoparticles after different catalytic cycle process. We researched the dehydrating ability and acid sensitivity of the Fe3O4 nanoparticles in the catalysis. Furthermore, 1,4-dithiane was synthesized by a cyclocondensation of Fe3O4 nanoparticles.The experimental results showed that: Fe3O4 nanoparticles prepared by hydrothermal method can be used as the catalyst for diethyl malate. The best condition of catalyst was the first cycle of 0.1 mmol Fe3O4 nanoparticles. The catalytic activity of Fe3O4 nanoparticles decreased with increasing of the catalytic cycles.
