中文摘要 | 本研究的目的在於利用相間轉移觸媒合成醋酸苯甲酯,研究中是以氯�磼M醋酸鈉 為原料進行反應,結果顯示反應速率會受到四級銨鹽的種類及用量、溶劑的極性、碘化鈉和 醋酸鈉用量等因素的影響。結果亦顯示三丁基胺及固定化四級銨鹽可取代四級銨鹽做為相間 轉移觸媒,催化醋酸苯甲酯的合成反應。 |
英文摘要 | In this study, benzyl acetate was synthesized from benzyl chloride and sodium acetate via the phase-transfer catalytic reaction. The results show that the reaction rates are influenced by the types and concentrations of quaternary ammonium salts, polarity of the organic solvent, and the amounts of sodium iodide and sodium acetate present. The results also revealed that tributylamine and polymer-supported quaternary ammonium salt can catalyze the synthetic reaction of benzyl acetate instead of quaternary ammonium salts. |
