摘要

本文旨在探討實驗自製四級銨化離子交換樹脂與商業化離子交換樹脂受到鹽類之影響，以瞭解此自製樹脂在合成化學催化劑之微觀行為。鹽類的種類含KOH，NaOH，NaCl和KCl等四種，採討變因有活性位置密度，溶劑種類及吸入化合物在樹脂之組成，樹脂之元素由掃描式顯微鏡（SEM-EDS）和元素分析儀（EA）進行分析，樹脂活性位置（氯離子濃度）由元素分析儀及Volhard定量分析法分別測得。實驗結果顯示自製樹脂在吸入溶劑組成都優於商業樹脂，化合物吸入（或吸附）現象可用Freundlish方程式描式。

The salt effect (KOH, NaOH, NaCl and KCl) of the lab-produced resins (lipophilic) and the commercial ion-exchange resin (hydrophilic) were investigated, including the density of active sites, kind of solvent, imbibed solvent composition of the resin. The element of the resin was analyzed by SEM-EDS and EA. The degree of quaternization (chloride density) in the resin was determined by EA and Volhard method. The imbibed amounts of organic solvent and water and the volume ratios for lab-produced resins were larger than those for commercial resins. The equilibrium relationship between interier salt concentration in the resin and bulk salt concentration was described by Freundlish isotherm equation.
