摘 要: 研究了利用多种相转移催化剂在不同实验条件下合成 β-萘乙醚。实验结果表明 :用四丁基氯化铵为相转移催化剂 ,当反应温度为 76℃ ,β-萘酚∶溴乙烷∶四丁基氯化铵 (摩尔比 )为 1∶ 1.2∶ 0 .0 7,反应时间为 7h时 ,产率高达 98.5 %。 Used various catalyst and under different conditions, the phase transfer catalytic synthesis of β naphthol ethylether was studied. The results showed that the yield was up to 98.5% by use of tetrabutylammonium chloride as catalyst and under the optimum conditions: β naphthol∶bromoethane∶tetrabutylammonium chloride=1∶1.2∶0.07(molar ratio),reaction temperature was 76℃, and reaction time was 7h.
