摘　　要：在相转移催化剂存在条件下,以对苯二甲酰氯（TPC）、间苯二甲酰氯（IPC）、苯酚、氢氧化钠为原料,通过界面反应合成高纯度的对苯二甲酸二苯酯（DPT）,m.p.为203.1-203.9℃,收率为98.3%;间苯二甲酸二苯酯（DPI）,m.p.为140.8-141.7℃,收率为98.5%.该方法具有反应条件温和、操作简单、溶剂和催化剂均可循环利用等优势,是一种具有工业化应用前景的绿色合成工艺.The purer DPT/DPI were synthesized by interfacial reaction of paraphthaloyl chloride （TPC）/isophthaloyl chloride（IPC） with phenol and sodium hydroxide in the presence of a phase transfer catalyst.The DPT＇s melting point was at the range of 203.1 - 203.9 ℃ with yield 98.3 %, and the DPI＇ s melting point was at the range of 140.8 - 141.7 ℃ with yield 98.5%. The green-technology which is attributed to industrial application is very temperated and simple while the solvent and catalyst can be recycled.
