2,4-二硝基苯基苄氧乙基醚的合成研究

Study on Synthesis of the 2,4-Dinitrophenyl Benzyloxy Ether

以苄氧乙醇和2,4-二硝基氯苯为原料经过醚化反应合成了2,4-二硝基苯基苄氧乙基醚。讨论了温度、苄氧乙醇、钠和2,4-二硝基氯苯的摩尔配比对收率的影响。结果表明,在温度20℃-30℃时,苄氧乙醇、钠和2,4-二硝基氯苯摩尔比为1.1:1.1:1.05时,苄氧乙醇反应较完全,2,4-二硝基苯基苄氧乙基醚的收率可达79.71%。最后通过1H-NMR和红外光谱对产品结构进行了表征。

2,4-Dinitrophenylbenzyloxy ether was synthesized from benzyloxyethanol and 2,4-dinitrochlorobenzene asthe starting materials through etherification reaction. Various reaction factors influencing the yield of the targetproduct were discussed. The result shows the following optimum reaction conditions： the molar ratio of benzy-loxyethanol, sodium and 2,4-dinitrochlorobenzene is 1.1：1.1：1.05, the reaction of temperature is 20 to 30？ and theyield of the product is up to 79.71%. The final product is characterized by means of IH-NMR spectrum and FT-IR spectrum.
