摘要:

本文合成了二取代苯甲醛-二-对-二氨基苯基甲烧类席夫碱类的7个化合物,并应用物理方法进行了表征.通过加热显微观察,这些化合物都具热色性,而其中4种具有可逆热色性.此外应用差热分析阐述了这类席夫碱的吸热峰的ΔHS)与其结构的关系.

Abstract:

Bis-substituted-phenylaldehyde-bis-(p-aminophenyl)methane-schiff base (SB) of general formula (R)-phCH=N-ph-CH2-ph-N=CHph(R),where R is p-NO2, m-NO2,p-OH, o-OH, p-Cl,-H, p-OCH3, were synthesized and characterized. They are thermolabile and undergo thermochrocism and thermal decomposition after melting. The TG. and DSC measurement were recorded in dynamic air and interpreted.

Key words: Bis-substituted-phenylaldehyde-bis-(p-aminophenyl)methane-schiff, base Synthesis, thermo-hrocis
