摘　　要：在吡啶／醋酸溶液中Ｆｅ￣（３＋）对Ｈ＿２Ｏ＿２氧化环己烷成环己酮略有催化作用，加入漆酚可使氧化产率显著提高到４０％～６０％，适当升高温度也能提高产率。溶剂组成对产率和选择性均有影响，最佳溶剂是摩尔比为２∶１的吡啶和醋酸组成的混合溶剂，此时主要产物是环己酮，选择性达９２％～９４％，其次为环己醇，但它不是该反应的中间产物。提出了可能的反应机理。The selective oxidation of cyclohexane by H_2O_2 using Fe￣(3+)with urushiol as catalyst in the pre-sence of pyridine and acetic acid has been studied systematically.It was shown that Fe￣(3+) alone was capableof catalyzing the oxidation of cyclohexane only with a low yield.However,the use of Fe￣(3+)with urushiol ascatalyst resulted in increasing the reaction yield up to 40%～60%.When temperature rose from 10 to 80℃the yield increased gradually.The solvent composition had a profound effect upon the reaction yield and se-lectivity for cyclohexanone.The optirnum solvent matrix was pyridine/acetic acid 2∶1 (molar ratio)whilethe selectivity for cyclohexanone was 92%～94%. Cyclohexanol was not the precursor of cyclohexanonebut a by-product.Apossible mechanisrn was proposed and discussed.
