双胺芴的合成方法研究

Studies On The Synthesis Of Aniline

摘要:

本文研究了双胺芴合成方法以及不同条件对反应的影响，探讨了不同酸盐的催化效果、催化剂用量、苯胺用量、反应温度、反应时间等因素对双胺芴产率的影响。实验结果表明，当n(苯胺)：n(PhNH2?HCl):n(芴酮)=10：1.5：1时，控制反应温度在130 ℃，反应6小时，双胺芴的产率最高为88.3%。

Abstract:

We study the synthesis of 9, 9-bis (4-aminophenyl) fluorene(BPF) and the effects reaction conditions such as different acid catalysts, mass of acid catalyst, mass of aniline, reaction temperature and reaction time on the yield of BPF were discussed. The test results showed that dehydarted by appropriate amout of toluene when n(aniline):n(HCl):n(fluorenone)=10:1.5:1, reaction temperature is 130 ℃, reaction time is 6 h, we can gain the highest rate of BDF to 88.3%.
