| Abstract: | 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. |
