中文摘要:
      采用简易化共沉淀氧化法,以盐酸酸洗碳钢废液为原料制备Fe3O4磁粉。通过反应过程中pH的变化监测反应溶液中的n(Fe3+)∶n(Fe2+),为氧化共沉淀法提供了简易化操作。比较了本文制备的小粒径Fe3O4与Alfa试剂级50~100 nm粒径的Fe3O4在香豆素衍生物和喹喔啉衍生物合成中的催化效果。采用振动样品磁强计、X射线衍射仪、TEM对制备的Fe3O4样品进行了表征;化合物的结构均经核磁共振波谱(NMR)和高分辨质谱(HRMS)确证。
英文摘要:
      The Fe3O4 magnetic powder was prepared with simple co-precipitation oxidation method using steel pickling waste liquor as raw material. The ratio of Fe3+∶Fe2+ in the reaction solution was monitored by the change of pH during the reaction process,which provided a simple operation for the co-precipitation oxidation method. The catalytic effect of Fe3O4 with small particle size and Alfa reagent grade of 50~100 nm on the synthesis of coumarin derivatives and quinoxaline derivatives was compared. The prepared Fe3O4 samples were characterized by VSM,XRD and TEM. The structures of the compounds were con-firmed by nuclear magnetic resonance spectroscopy (NMR) and high resolution mass spectrometry (HRMS).
