An efficient sonochemical protocol for the nitration of aromatic compounds was described in the presence of a catalytic amount of sulfuric acid-functionalized silica-based core/shell magnetic nanocomposite at room temperature in an eco-friendly and recyclable media, deep eutectic solvent (DES), based on choline chloride and urea. The particle size, morphology and elemental analysis of the core/shell nanocatalyst were carried out by TEM, SEM, EDX and XRD analyses. The nanocatalyst and DES were easily recovered from the reaction mixture quantitatively and reused several times.
在基于氯化胆碱和尿素的深共熔溶剂（DES）这种环保且可循环利用的介质中，于室温下描述了一种在催化量的硫酸功能化二氧化硅基核壳磁性纳米复合材料存在下对芳香族化合物进行硝化的高效声化学方法。通过透射电子显微镜（TEM）、扫描电子显微镜（SEM）、能谱仪（EDX）和X射线衍射（XRD）分析对核壳纳米催化剂的粒径、形态和元素分析进行了研究。纳米催化剂和DES能够很容易地从反应混合物中定量回收并重复使用多次。
