摘要
以β-萘酚和水合肼为原料经水热反应合成联萘胺,对粗产品的提纯方法进行了改进,提出了一种以二甲基亚砜/水/乙醇为溶剂(体积比15∶60∶40)的新的纯化方法,简化了联萘胺的提纯步骤,产率可达55%。
2,2'-Diamino-1,1 ' -binaphthyl was synthesized by hydrothermal reaction from β-naphthol and hydrazine hydrate. The raw product was purified by a new method which using DMSO/water/ethanol( 15 : 60 : 40) as solvent. The purification procedure was simplified compare with literature method, with a production of 55 %.
