Abstract:

Oxidation catalysts of organic sulfide were synthesized by the ferromagnetic Fe3O4 matrix and phosphotungstic acid urea complexes(PAUC). The properties of products were characterized by IR, XRD, Raman and TG. With introduction of oxidation catalysts of organic sulfide, it is found that PAUC exists on Fe3O4 support in a Keggin structure and there is a chemical bond effect between them. If the H2O2 oxidation of ethanethiol proceeds in n-hexane, the oxidation activity of ethanethiol over ferromagnetic Fe3O4 matrix is increased in the presence of the PAUC. The effect of urea on activity has been discussed.
