摘　　要：合成了5种Dowson型杂多酸催化剂(Pn),并用于催化H2O2氧化蒽制备蒽醌的反应。结果表明H8[P2Mo14V4O62H2](P5)的催化活性最好。最佳的氧化反应条件为:蒽5.6mmol,n(蒽)∶n(H2O2)=1∶11,P530mg,溶剂正丁醇,于70℃反应1h,产率达93.2%。Five kinds of Dowson hereopoly acids （P^n） were prepared and then used as catalysts to oxidize anthracene into anthraquinone with H2O2. The results showed that Hs [ P2Mo14V4O62H2] （pS） exhibited best catalytic activity. The optimal oxidation conditions at 70 ℃ for 1 h were as follows ： anthracene was 5.6 mmol; n（ anthracene） ：n（H2O2） was 1：11; pS was 30 mg; solvent was n-butyl alcohol. The yield was 93.2% under optimal oxidation conditions.
