英文摘要: The Dawson-type polyoxotungstate emulsion catalysts Q(18)P(2)W(18), Q(18)P(2)W(17), and Q(18)P(2)W(12) were successfully synthesized and characterized by IR and (31)P 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 H(2)O(2) as an oxidant under mild conditions. The activity of the catalysts decreased in the order: Q(18)P(2)W(12) > Q(18)P(2)W(17) > Q(18)P(2)W(18). The oxidative reactivity of the sulfur-containing compounds decreased according to DBT > 4,6-DMDBT > BT > 2,5-DMT. BT was completely oxidized into the corresponding sulfone upon catalysis by Q(18)P(2)W(12) at 60 degrees C for 30 min.
