摘要
利用溶胶 凝胶 (Sol gel)技术制备了新型的有机 /无机杂化材料担载的季铵盐催化剂。优化了制备方法、反应条件等多种因素 ;考察了其作为相转移催化剂在 1 溴代正庚烷与碘化钾的亲核取代反应中的应用 ,转化率最高可达到 95 %。
A novel type of catalysts, organic/inorganic hybrid supported quaternary ammonium salts, was prepared by the Sol-gel technology and its catalyzing activity for the PTC(phase transfer catalysis) reaction between 1-bromoheptane and potassium iodide was investigated. The highest conversion of this PTC reaction could reach up to 95% by optimizing the preparation method and the reaction conditions.
