摘　　要：采用超声波作用下的相转移催化技术合成了香原料β萘乙醚。经正交实验确定了最佳条件为：β萘酚∶溴乙烷∶四丁基溴化铵＝１４∶１０∶００３（摩尔比），反应温度７５℃，反应时间５ｈ。产品纯度９９８％，产率可达９４２％，比传统的硫酸催化法（６０％）和常规的相转移催化法（８４６％）的产率都高。A perfume material,βnaphthal ether,was synthesized by means of ultrasonic phase transfer catalysis(PTC) method.The optimum reaction conditions that were obtained by using orthogonal experiment were shown as follows:the ratio of βnaphthal ether to ethane bromide to tetrabutyl ammonium bromide was 1.4∶1.0∶0.03,the reaction temperature was 70～75℃ and the reaction time continued for 5 hours.The optimum production yield could be 94.2% which was higher than that of traditional sulfuric acid catalysis (60%)and ordinary PTC method (84.6%),and the purity determined by gas chromatography was 99.8%.
