β-萘丁醚的合成

SYNTHESIS OF βNAPHTHOL BUTYL ETHER

用 β 萘酚和正丁基溴在二甲基亚砜溶剂中缩合反应合成 β 萘丁醚。对反应条件进行了研究 ,结果表明最佳反应条件为 :β 萘酚与正丁基溴的物质的量比为 1∶ 1 .6,以 KOH为碱剂 ,反应温度 90～ 95℃ ,反应时间 2 .5 h,β萘丁醚产率达 95 .5 %

Naphthol butyl ether was synthesized from β naphthol and n butyl bromide in solvent DMSO. The results showed that when the molar ratio of β naphthol to n butyl bromide was 0.018∶ 0.030, DMSO 20 mL, KOH 2 g, reaction temperature 90~95 ℃, reaction time 2.5 h, the yield of β naphthol butyl ether was 95.5 %.
