超声波辅助合成3,5-二碘代水杨醛及希夫碱配体

Ultrasound-assisted Synthesis of 3,5-diiodo Salicylaldehyde and Schiff Base Ligand

研究超声波技术在3,5-二碘代水杨醛合成中产生的影响,经过单因素实验获得最佳反应条件:1 h机械搅拌,超声波水浴环境,温度70℃,水杨醛∶碘酸钾∶碘化钾=1∶1∶1,产率为92.48%。在超声波环境下继续合成3,5-二碘代水杨醛缩苯胺、3,5-二碘代水杨醛缩乙二胺两种希夫碱配体。利用红外光谱对以上三种化合物进行了表征。本方法反应物易得,反应效率高,反应条件温和,操作简单,超声波的辅助大大地提高了反应的产率。

Aiming to search the effect of ultrasound technology generated in 3,5 - diiodo salicylaldehyde synthesis, we through the single factor experiment to get the best reaction conditions： lh mechanical agitation, ultrasonic bath environment,the temperature is 70 ℃, Salicylaldehyde： KIO3 ： KI is 1 ： 1 ： 1, and the yield was 92.48%. In the ultrasonic environment continues to synthesize 3,5 - diiodo - sallcylaldehyde aniline, 3,5 - diiodo - salen two Schiff base ligands. Using infrared spectroscopy to characterize these three compounds. This method is easy to get the reactants, high reaction efficiency, mild reaction conditions, and the operation is simple. The help of ultrasonic greatly improve the yield of the reaction.
