the morphological, chemical and physical properties of the prepared nanocatalyst. All these results confirmed the successful synthesis of Fe3O4@PVA-SO3H. This heterogeneous nanocatalyst was then successfully used for the synthesis of α-aminonitrile derivatives by starting from an aldehyde, an aniline and trimethylsilyl cyanide (TMSCN). High efficiency, green chemistry properties, simple and easy separation
本研究描述了一种基于聚乙烯醇(PVA)的新型磁性纳米复合材料的设计,制备和表征,该复合材料是无毒,水溶性,高机械稳定性和低成本的聚合物。傅里叶变换红外(FT-IR)光谱,场发射扫描电子显微镜(FE-SEM)图像,透射电子显微镜(TEM)图像,X射线衍射(XRD)模式,能量色散X射线(EDX)分析用热重(TG)分析法描述了所制备纳米催化剂的形貌,化学和物理性质。所有这些结果证实了Fe 3 O 4 @ PVA-SO 3的成功合成。H.这种多相纳米催化剂随后通过从醛,苯胺和三甲基甲硅烷基氰化物(TMSCN)开始成功地用于合成α-氨基腈衍生物。高效,绿色化学性质,简单容易的分离是这种纳米复合材料的特殊性质。Fe 3 O 4 @ PVA-SO 3 H可以通过外部磁体产生,可以重复使用十次,而不会改变其结构。
