摘要
应用二乙烯苯交联的聚苯乙烯－聚乙二醇４００（ＤＶＢ－ＰＳ－ＰＥＧ－４００）树脂作相转移催化剂催化合成了１，４－二乙氧基苯，并用红外光谱、元素分析对产物进行了测定。此法具有产率高，易操作，反应条件温和，催化剂能重复使用，效果良好的优点。
The synthesis of 1,4 Diethoxybenzene was studied using insoluble Polystyrene Supported PEG as tri phasic catalyst. The method has the advantages of good yield (86%), easy operation, mild reaction, and the catalyst could be reused efficiently. Its structure was characterized by IR and elemental analysis.
