摘　　要：研究了β-萘酚与溴乙烷在聚乙二醇存在下的反应。考查了β-萘酚与溴乙烷的物质的量比、催化剂种类和用量等因素对β-萘乙醚产率的影响。结果表明,在β-萘酚与溴乙烷的摩尔比为1∶1,反应时间1.7 h,β-萘乙醚的产率达95.4%。β-Naphthol ethyl ether was prepared by the reaction of β-naphthol with bromic ether in the presence of polyethylene glycol. The effect of different factors such as the amount of catalyst, the molar ratio of β-naphthol to bromic ether, reaction time and etc. on yield of β-naphthol ethyl ether was carefully studied. When the molar ratio of β-naphthol to bromic ether was 1 ： 1 and the reaction time was 1.7 h, the yield of β-naphthol ethyl ether was 95.4%.
