摘要： The present invention relates to a process for preparing hydroxylated aromatics by using hydrogen and oxygen and more particularly, to a process for preparing hydroxylated aromatics by using hydrogen and oxygen with a two-component heterogeneous catalyst. One component consists of porous catalyst containing one of Group VIII B transition metals such as Pd, Pt, Au and Cu, and hydrogen transfer organic compounds such as anthraquinone. The other component consists of a catalyst containing a transition metal selected from Ti, V, and Sn with tetrahedral coordination geometry. The main advantages of this new catalytic system are to 1) overcome the drawbacks of liquid phase oxidation using conventional homogeneous catalysts, 2) avoid use of expensive hydrogen peroxide as an oxidant, and 3) improve the selectivity of the reaction.

摘要： The invention herein relates to a direct manufacturing method of hydrogen peroxide over zeolite, wherein transition metals such as palladium or platinum, and organic compounds such as 2-alkyl anthraquinone or the like are encapsulated onto the zeolite channels, and then reducing agents such as hydrogen, ammonia or alcohol are used in the reaction temperature range of 10.about.90.degree. C. under atmospheric pressure. In general, alkyl anthiraquinone used in the conventional manufacturing, method of hydrogen peroxide can be easily hydrogenated in a relatively mild temperature condition in the range of room temperature to 100.degree. C. by means of a compound having hydrogen. However, the use of alkyl anthraquinone in the reaction is problematic due to the fact that it can only be utilized in a working solution with a solvent which can effectively dissolve alkyl anthraquinoe. The invention herein provides a method of directly manufacturing hydrogen peroxide in aqueous solution, which can overcome the problems of the conventional methods, wherein the compounds which can transfer hydrogen such as alkyl anthraquinone or the like are encapsulated onto the zeolite pores.
摘要翻译：本发明涉及在沸石上的过氧化氢的直接制造方法，其中将过渡金属如钯或铂，以及有机化合物如2-烷基蒽醌等包封在沸石通道上，然后还原剂如氢在大气压下在10℃-10℃的反应温度范围内使用氨或醇。通常，在常规制造中使用的烷基蒽醌可以在相对温和的温度条件下在室温至100℃的范围内通过具有氢的化合物容易地氢化。然而，在反应中使用烷基蒽醌是有问题的，因为它只能用于能够有效溶解烷基蒽醌的溶剂的工作溶液中。本发明提供了一种在水溶液中直接制造过氧化氢的方法，其可以克服常规方法的问题，其中可将氢转移的化合物如烷基蒽醌等包封在沸石孔中。
