摘要
本文选用分子量400、600和800的聚乙二醇作相转移催化剂合成对硝基苯甲醚。研究了几种因素对反应的影响,确定了最佳反应条件,并导出了反应速率方程式。证明了聚乙二醇作为催化剂能够适用于有水存在的反应,并揭示氢氧化钠浓度影响反应的原因。
The effect of several parameters has been experimentally investigated on synthesizing p-nitroanisole from p-nitrochlorobenzene in the presence of PEG as phase transfer catalyst.The results show that PEG is an effective phase transfer catalyst in this reaction.We have discovered that the concentration of sodium hydroxide affects the extraction equilibrium constant of PEG between aqueous phase and organic phase.
