【摘要】 以苯酚为原料在催化剂作用下用双氧水直接进行氧化羟基化是合成对苯二酚和邻苯二酚的主流生产工艺，其中催化剂是过程效率的关键。催化剂的组成与结构以及反应工艺条件均会极大影响催化剂的羟基化性能。基于此，以Fe基MFI型分子筛为研究对象，构建了一个面向化学、化工本科生的教学实验，重点考察Fe基催化剂的制备条件(如活性金属Fe含量、分子筛硅铝比)与反应温度对其催化苯酚羟基化性能的影响规律，旨在揭示催化剂的“构效关系”。此举实现了前沿科学研究与本科实验教学的无缝对接，能有效拓宽学生知识面，激发其创新思维，并全面提升学生的科研实践能力。更多还原

【Abstract】 The mainstream industrial process for synthesizing hydroquinone and catechol involves the direct oxidative hydroxylation of phenol using hydrogen peroxide in the presence of a catalyst, where the catalyst plays a critical role in determining process efficiency. Both the composition and structure of the catalyst, as well as the reaction conditions, significantly influence its hydroxylation performance. Based on this, a teaching experiment targeting chemistry and chemical engineering undergraduates was designed, focusing on Fe-based MFI-type zeolites. This experiment systematically investigates the effects of catalyst preparation conditions, such as active iron content and zeolite silicon-to-aluminum ratio, and reaction temperature on the performance of Fe-based catalysts in phenol hydroxylation, aiming to elucidate the “structure-activity relationship” of the catalysts. This initiative achieves seamless integration of cutting-edge scientific research with undergraduate experimental teaching, effectively broadening students’ knowledge, stimulating their innovative thinking, and comprehensively enhancing their scientific research capabilities.更多还原
