| Abstract: | The Dawson-type polyoxotungstate emulsion catalysts Q18P2W18,Q18P2W17,and Q18P2W12 were successfully synthesized and characterized by IR and 31P MAS NMR. They were used for the oxidation of sulfur-containing compounds such as 4,6-dimethyldibenzothiophene(4,6-DMDBT) ,dibenzothiophene(DBT) ,benzothiophene(BT) ,and 2,5-dimethythiophene(2,5-DMT) with H2O2 as an oxidant under mild conditions. The activity of the catalysts decreased in the order: Q18P2W12 > Q18P2W17 > Q18P2W18. The oxidative reactivity of the sul... |
