【摘要】 制备了3种不同钒含量的磷钼钒杂多酸。通过IR、UV/VIS、XRD、TG、EPMA表征HmPMo12-nVnO40具有Keggin结构。HmPMo12-nVnO40作为催化剂用于环己烷羟基化反应的结果表明,H5PV2Mo10O40·5H2O杂多酸催化氧化环己烷的转化率为11%,环已酮、环已醇的总产率为10%。HmPMo12-nVnO40杂多酸是一种具有潜力的环己烷氧化反应催化剂。更多还原

【Abstract】 This paper describes the synthesis of three kinds of P-Mo-V heteropoly acids（HPAs） with differert number of V atoms. They are characterized by IR,UV/VIS,XRD,TG,EPMA to be of Keggin structure. Using H_mPMo_12-nV_nO₄₀ as catalysts in cyclohexane, the H₅PV₂Mo₁₀O₄₀·5H₂O is most active, with 11% of cyclohexane conversion and 10% yield of cyclohexanol and cyclohexanone. It indicates (H_mPMo_12-nV_nO₄₀) being a prospective catalyst for cyclohexane oxidation.更多还原
