β,β'-联萘酚的合成研究

Study on synthesis of 2,2′-dihydroxy-1,1′-dinaphthalene

简要地介绍了β,β′联萘酚的基本性能和用途,对以乙醇为溶剂合成β,β′联萘酚的工艺进行了研究。结果表明最佳的反应条件是n(β萘酚)∶n(FeCl3·6H2O)=1∶2,反应时间为2.5h,反应温度65℃。在此条件下,联萘酚的收率达90%以上。

The basic properties and applications of 2,2′ dihydroxy 1,1′ dinaphthalene were described compendiously. A synthetic method of 2,2′ dihydroxy 1,1′ dinaphthalene with ethyl alcohol as solvent was studied. The experimental results showed that the optimal reaction conditions were: n (β naphthol)∶ n (FeCl 3·6H 2O)=1∶2,under reaction temperature of 65℃ for 2.5 hours . The yield of the final product was over than 90% with good property.
