微波辅助催化合成苯乙醚的探讨

Microwave assisted catalytic synthesis of phenetole

在微波辐射和相转移催化剂十六烷基三甲基溴化铵的作用下,采用酚钠盐与溴乙烷反应合成了苯乙醚。实验讨论了微波辐射功率、辐射时间、反应温度、催化剂种类等因素对苯乙醚合成的影响。结果表明,在相转移催化剂的存在下,用微波辅助催化,可使苯乙醚合成反应时间缩短,且收率显著提高。

The phenetole was synthesized by the reaction of phenol salt with bromoethane under microwave irradiation using hexadecyl trimethyl ammonium bromide as phase transfer catalyst. The effect of the synthetic conditions on the obtained compound such as microwave power, reaction time, reaction temperature, and type of catalyst were also investigated. The results show that the advantages of the present procedure are high yields and short reaction time.
