| 摘 要： | 从乙酰苯胺出发,经氯磺化、氨解、水解、重氮化、偶联等步骤制得了11个偶氮磺酰胺及偶氮磺酰胺席夫碱类化合物,目标化合物经IR,1HNMR和元素分析确证了分子结构,并用差热分析仪(DTA)测定了其变温范围,在180～200℃有变色峰存在,与目测法结果相符,证明该类化合物为一类不可逆热致变色化合物。

| Abstract: | Eleven azosulfonamides and azosulfonamide Schiff bases w er e synthesized using acetanilide as starting material through chlorosulfonation, ammonolysis,hydrolysis,diazotization and coupling reactions.Structures of these compounds were confirmed by IR,1HNMR and elementary analysis.Their thermochro mic temperatures were measured by DTA,and thermochromic peaks were found between 180 and 200 ℃,which was consonant with the observed result by eyes directly.Th is demonstrats that these compounds are a kind of irreversible thermochromic com pounds. |
