以铁卟啉为催化剂 ,在 Na OH/CH3OH中加入 H2 O2 溶液 ,可将 1 -萘酚和 2 -萘酚高选择性氧化成 2 -羟基 -1 ,4-萘醌 (HNQ) .UV-Vis图可观察到铁卟啉与 H2 O2 形成的氧 -高价铁卟啉化合物 ;由吸收光谱的变化 ,可确定金属卟啉中间体形成的平衡常数 .由 HNQ浓度随时间变化的关系 ,可确定 HNQ的形成与分解均为 1级反应
With iron porphyrin as catalyst, H2O2 solution was added to NaOH / CH3OH to oxidize 1 - naphthol and 2 - naphthol to 2 - hydroxy - 1, 4 - naphthoquinone (HNQ) Vis Figure Oxygen-high-valent iron porphyrin compounds formed by iron porphyrin and H2O2 can be observed. The equilibrium constants formed by the metalloporphyrin intermediates can be determined by the change of absorption spectra. The relationship between the concentration of HNQ and time can be determined HNQ formation and decomposition are level 1 reaction
