1,4-二(对氟苯甲酰基)苯的合成与纯化

Synthesis and purification of 1,4-bis (4-fluorobenzoyl) benzene

1,4-二(对氟苯甲酰基)苯是合成聚芳醚酮的单体之一,采用付-克酰化反应合成了1,4-二(对氟苯甲酰基)苯,并采用红外光谱(IR)、元素分析、差示扫描量热仪(DSC)和核磁共振谱(1H-NMR)对产物结构进行了表征。

1,4-bis （4-fluombenzoyl） benzene （1,4-FBB）, one of monomers for polyetherketone, was synthesized using fluorobenzene and terephthaloyl dichloride as raw materials, and the yield of the 1,4-FBB was 92%. The final product was characterized by F＇rIR, element analysis, DSC and ^1H-NMR.
