聚苯乙烯固载聚乙二醇催化合成2-萘乙醚的研究

Catalytic Synthesis of 2-Naphthyl Ethyl Ether by Polyethylene Glycol Supported on Polystyrene

以 2 -萘酚和溴乙烷等为原料 ,聚苯乙烯固载聚乙二醇 - 4 0 0为相转移催化剂合成了 2 -萘乙醚。考察了影响产品收率的因素 ,最佳反应条件为 :溴乙烷 :2 -萘酚 :催化剂为 1.4mol∶1mol∶2 4 g ,反应在回流温度下进行 ,反应时间3.0h ,收率可达 90 .4 % 。

Naphthyl ethyl ether was synthesized with 2-naphthol and ethyl bromide as raw material and polyethylene glycol supported on polystyrene as catalyst.The factors that influence on the reaction were discussed and the best conditions were found out.The optimum conditions are:ethyl bromide:2-naphthol∶catalyst is 1.4mol∶1mol: 24g;reaction temperature is reflux temperature;reaction time is 3.0h.The yield is above 90.4% under the optimum conditions.Catalyst can be used repeatedly.
