    • PURPOSE: A heterogeneous catalyst for preparation of para-benzoquinone and catechol and a preparation method using the same are provided to prepare para-benzoquinone and catechol of 90 weight% or greater based on the weight of a total product from a reaction of phenol and hydrogen peroxide in an organic solvent by using a heterogeneous catalyst. CONSTITUTION: A heterogeneous catalyst for preparation of para-benzoquinone and catechol includes a porous carrier. The porous carrier carries at least one metal ion selected from the group consisting of vanadium and copper. The porous carrier further carries at least one metal ion selected from alkali metals. The vanadium and copper ions are supplied from a nitrate, a sulfate, an acetate, or a halogen salt. A preparation method using the heterogeneous catalyst for preparation of para-benzoquinone and catechol prepares 90 weight% or more of para-benzoquinone and catechol based on the total weight of a product produced from a reaction of phenol and hydrogen peroxide in an organic solvent.
    • 目的:提供用于制备对苯醌和儿茶酚的非均相催化剂及其制备方法,以制备基于酚和氢的反应的总产物重量为90重量%或更高的对苯醌和邻苯二酚 过氧化物通过使用多相催化剂在有机溶剂中。 构成:用于制备对苯醌和邻苯二酚的非均相催化剂包括多孔载体。 多孔载体携带至少一种选自钒和铜的金属离子。 多孔载体还携带至少一种选自碱金属的金属离子。 钒和铜离子由硝酸盐,硫酸盐,乙酸盐或卤素盐提供。 基于由苯酚和过氧化氢在有机溶剂中的反应产生的产物的总重量,使用非对称催化剂制备对苯醌和儿茶酚的制备方法制备了对苯醌和邻苯二酚的90重量%或更多。
