5-(4’-磺胺苯基偶氮)水杨醛席夫碱的合成及其热色性研究

Studies on the synthesis and thermochromism of 5-(4'-sulphamidylbenzylazo)salicylaldehyde Schiff bases

以乙酰苯胺、水杨醛、胺类为原料 ,经氯磺化、氨解、重氮化、偶联和缩合反应 ,合成了 9种新的偶氮磺胺类席夫碱化合物 ,利用红外光谱、核磁共振氢谱和元素分析等对其结构进行了确认 。

Nine novel 5 (4' sulphamidylbenzylazo)salicylaldehyde Schiff bases are prepared by using sulfanilamide,salicylaldehyde and aromatic amine as initial materials.The structures of these compounds are characterized by IR, 1H NMR,MS and element analysis.The studies on thermochromic properties of these compounds are also performed.
