摘要 以3-氨基-4-甲氧基苯磺酸、2-氨基噻二唑、2-氨基-5-甲基噻二唑、2-氨基噻唑、2-氨基-4,5-二甲基噻唑等为原料合成了四种尚未见报道的偶氮化合物,通过UV-vis、FT-IR、MS、1H-NMR等方法对这4种化合物的结构进行了表征,并研究了它们的的电子吸收光谱行为及热稳定性。 Four novel benzenesulfonic azo compoumds were synthesized from 3 - amino - 4 - methoxy - benzenesul- fonic acid, 2 - amino - thiadiazole, 2 - amino -5 - methoxy - thiadiazole, 2 - amino - thiazole, 2 - amino -4,5 - dimethyl - thiazole. The four benzenesulfonic acid azo compoumds are 2 - [2 - (thiazole) azo] - 4 - methoxy - 5 - N - ethyl - aminobenzenesulfonic acid ( Azo - 1 ) ,2 - [2 - (4,5 - dimethyl - thiazole ) azo ] - 4 - methoxy - 5 - N - ethyl - aminobenzenesulfonic acid ( Azo - 2 ), 2 - [2 - ( 5 - ethyl - 1,3,4 - thiadiazole) azo ] 4 - methoxy - 5 - N - ethyl - - aminobenzenesulfonic acid ( Azo - 3 ), and 2 - [2 - ( 1,3,4 - thiadiazole ) azo ] 4 - methoxy - 5 - N - ethyl - - aminobenzenesulfonic acid (Azo - 4). They are characterized by FT - IR, MS, ^1 H - NMR. Their electronic absorption spectrum and thermal stability are investigated.
