This paper studies the synthesis of β-naphthyl ethyl ether under microwave radiation with β-naphthol and anhydrous alcohol as raw material and concentrated sulfuric acid as catalyst. It also explores the effects of reaction condition upon the yields. 研究了以β萘酚、无水乙醇为原料,浓硫酸为催化剂,采用微波辐射方法合成β萘乙醚,并探索了反应条件对产物产率的影响。
