Abstract	간단한 Keggin형의 텅스텐과 몰리브덴의 헤테로 다중산인, H₃PW₁₂O₄₀과 H₃PMo₁₂O₄₀는 표준식수에서 34% 과산화 수소와 함께 알코올의 산화를 위한 수분-관용적인 촉매로 사용되어졌다. 우리의 실험결과에 따르면 H₃PW₁₂O₄₀는 좋은 수율로 표준식수에서 치환을 위한 간단하고, 효과적이고, 값싼 촉매로 사용되어질 수 있다. 반응 과 정 중 25-80 oC에서 다른 용매 효과와 촉매의 농도변화와 기질 또한 연구하였다. Simple Keggin type tungsten and molybdenum heteropoly acids, H₃PW₁₂O₄₀ and H₃PMo₁₂O₄₀, were used as water-tolerant catalysts for the oxidation of alcohols with 34% hydrogen peroxide in normal drinking water. According to our findings, H₃PW₁₂O₄₀ may be used as a simple, effective, and cheap catalyst for this type of transformation in normal drinking water with excellent yields. Effects of different solvents at 25-80 oC and changing concentration of catalyst and substrate on the reaction progress were also studied.
