摘要
就含有醚键的双酚芴型二酐单体的合成加以研究,本文利用芴酮和苯酚合成了双酚芴单体,在此基础上与50%的KOH溶液成盐,然后在相转移催化剂四丁基溴化胺的作用下与N-甲基-4-硝基酞酰亚胺发生亲核取代反应,生成比较重要的单体双酚芴型双醚酞酰亚胺[1]。但是在双酚芴钾盐和N-甲基-4-硝基酞酰亚胺发生亲核取代生成双醚酞酰亚胺的产品非常少,一方面合成方案还有待于改进,另一方面是产品的后处理应找到合适的方法。
The synthesis of bisphenol fluorene dianhydride type monomer containing the ether bond was reported.Bisphenol fluorene monomer was turned its potassium salt by adding potassium hydroxide solution into the bisphenol fluorene.Under the catalysis of tetrabuty lammonium bromide as phase transfer catalyst,diether phthalimide was synthesized by reaction of the potassium salt of bisphenol fluorene and N-methyl-4-nitro-phthalicimide.But the potassium salt of bisphenol fluorene and N-methyl-4-nitro-phthalicimidenucleophiles occurred to replace the generation of diether phthalimide,which had not occurred very well,the result was not as good as expected,and less than ideal.The program of synthesis was needed to be improved,and a suitable post-processing method was also in great need.
