4-苯偶氮水杨醛腙类试剂的合成及其光谱研究

Synthesis of 4-(Benzeneazo) Salicyladelhyde Hydrazones and Study on Their Spectral Properties

用苯胺与水杨醛反应合成了4苯偶氮水杨醛,用苯甲酸乙酯、对羟基苯甲酸甲酯与水合肼反应,合成了苯甲酰肼、对羟基苯甲酰肼,然后用4苯偶氮水杨醛与苯甲酰肼、对羟基苯甲酰肼、苯肼、异烟肼反应,合成了四种新的4苯偶氮水杨醛腙类试剂。研究了这四种腙类试剂的红外光谱、紫外光谱、荧光光谱特性。

4-（benzeneazo） salieyladelhyde was synthesized with aniline and salicylaldehyde. Benzoylhydrazine and p-hydroxy- benzoylhydrazine were synthesized using the reaction of ethyl benzoate and methyl p-hydraxy benzoate with hydrazine hydrate. Four novel 4-（benzeneazo） salieyladelhyde hydrazones were synthesized using the reaction of 4-（benzeneazo） salieyladelhyde with benzoylhydrazine, p-hydroxybenzoylhydrazine, phenylhydrazine, and isonicotinyl hydrazine respectively. IR, UV and the fluorescence spectrum of 4-（benzeneazo） salieyladelhyde hydra,zones were studied.
