Dual amphiphilic catalyst, paratungstate X and heteropoly acidic salts Y with two defects were synthesized. IR, UV, single crystal diffraction and TG were used to investigate the structure.  After the oxidation sweetening simulation of  diesel oil, it was found that  emulsion systems had good oxidation effect on organic sulfide of different types and concentration,  dibenzothiophene and its derivatives  were more easily oxidized than benzothiophene and its derivatives,  and the rate of oxidation reaction was accelerated as the sulphide concentration increased under the appropriate condition (50 ℃, O:S mole ration 5:1).
仅供参考。
