In this study, SOH@zeolite-Y was synthesized by the reaction of chlorosulfonic acid with zeolite-NaY under solvent-free conditions, which was then supported by FeO nanoparticles to give SOH@zeolite-Y (FeO/SOH@zeolite-Y) magnetic nanoparticles. Several techniques were used to evaluate the physical and chemical characterizations of the zeolitic nanostructures. FeO-loaded sulfonated zeolite was applied as a novel multi-functional zeolite catalyst for the synthesis of imidazole and perimidine derivatives. This efficient methodology has some advantages such as good to excellent yield, high purity of products, reusability of nanocatalyst, simple reaction conditions, environmental friendliness and an economical chemical procedure from the viewpoint of green chemistry.
在本研究中，在无溶剂条件下通过氯磺酸与沸石-NaY反应合成了SOH@沸石-Y，然后用FeO纳米颗粒负载得到SOH@沸石-Y（FeO/SOH@沸石-Y）磁性纳米颗粒。采用多种技术对沸石纳米结构的物理和化学特性进行了评估。负载FeO的磺化沸石被用作合成咪唑和嘧啶衍生物的新型多功能沸石催化剂。从绿色化学的角度来看，这种高效方法具有一些优点，如产率良好至优异、产物纯度高、纳米催化剂可重复使用、反应条件简单、环境友好以及化学过程经济。
