analysis (XRD), scanning electron microscopy (SEM), and pore size distribution analysis. Crossed-aldol condensation of an aromatic aldehyde with cycloalkanone in the presence of these nanoparticles produced α, ά-bis(substituted-benzylidene) cycloalkanones in good yields without using any solvent. The present method is operationally simple and dosed not use organic solvent, which makes the process environmentally
摘要:本研究采用可控、简便的微波法将Sr(
NO3)2负载于天然膨润土上合成了SrCO3@
蒙脱土纳米复合材料。SrCO3@
蒙脱石纳米粒子的特性通过红外光谱 (IR)、能量色散 X 射线分析 (EDX)、X 射线衍射分析 (XRD)、扫描电子显微镜 (
SEM) 和孔径分布等先进技术进行鉴定分析。在这些纳米颗粒的存在下,芳香醛与环烷酮的交叉醛醇缩合以良好的收率产生α,α-双(取代的亚苄基)环烷酮,而无需使用任何溶剂。本方法操作简单,不使用有机溶剂,对环境无害。
