双邻香草醛席夫碱的合成与表征

Synthesis and Characterization of Bis-(o-vanillin)benzoic Imine Schiff Base

用邻香草醛,4,4-二氨基二苯醚为原料合成双邻香草醛(二苯醚)苯亚胺Schiff碱,这是一种具有N,N,O,O-四齿配位的新型Schiff碱,通过红外光谱、紫外光谱,核磁、粉末XRD衍射等对其结构进行了表征。结果表明:在无水乙醇中成功合成了双邻香草醛(二苯醚)苯亚胺Schiff碱,且生成的Schiff碱为晶态物质,熔点为170～172℃。

Bis- （O-vanillin） benzoic imine schiff base was synthesized with o-vanillin and 4,4＇-diaminodiphenyl ether as raw materials in ethanol,which is a new type of schiff base with N,N,O,O - four teeth coordinate. Through IR, UV, NMR, XRD diffraction and so on, the structures of the schiff base were characterized. The results showed that it is a kind of crystalline material, its melting point is 170 - 172 %.
