摘　　要：以纳米固载杂多酸H3PW12O40/SiO2为催化剂,β-萘酚和无水乙醇为原料,合成了β-萘乙醚,并研究了各种因素对产品收率的影响.该反应的最佳条件是:在酚醇物质的量比为1∶3.5,催化剂用量为0.6 g/0.04 molβ-萘酚,反应时间的7 h,β-萘乙醚的收率可达65.81%.β-naphthyl ethyl ether is synthesized from β-naphthol and ethyl alcohol by using nanometer complex heteropoly acid as catalyst. The factors influencing the synthesis are discussed and best conditions are found out. The optimum conditions are： molar ratio of β-naphthol to ethyl alcohol is 1：3.5, the amount of catalyst is 0.6g/0.04mol β-naphthol, the reaction time is 7h. the yield can reach up to 65.81%.
