1,4-双-(4'卤苯酰基)苯合成及提纯改进的研究

Study on Synthesis and Purification of 1,4-Bis-(4-balidebenzoyl) benzene through Modified Method

以对苯二甲酰氯和卤代苯为单体,无水氯化铝粉末为催化剂合成了1,4-双-(4'卤苯酰基)苯。运用改进的方法提纯得到精制品1,4-双-(4'卤苯酰基)苯,收率96%。并通过1HNMR和DSC对产物进行表征,测试结果与目标产物相吻合。

1,4-Bis-（4-chlorobenzoyl） benzene was synthesized with terephthaloyl chloride and chlorobenzene （or bromobenzene）,and aluminum chloride as catalyst. 1,4-Bis-（4-chlorobenzoyl）benzene was purified through modified method with a yield 96%. The strcture was characterized by means of ^1H NMR and DSC spectroscopy. The results showed an agreement with the proposed structure.
