Abstract

Di-Schiff’s bases are normally synthesized from aldehyde and diamine using organic solvents under conditions that remove water azeotropically. Here is a report for the preparation of di-Schiff’s base using both the conventional method and pure water without a catalyst and results were compared. It was observed that yields are better and reaction time is comparatively less when water is used as a solvent. Keywords: Benzene, Water, Green chemistry.

以苯和水(绿色化学的概念)为溶剂合成迪希夫碱的比较研究
迪希夫碱通常是用有机溶剂在共沸脱水条件下由醛和二胺合成的。本文报道了用常规方法和不加催化剂的纯水制备迪希夫碱的方法,并对结果进行了比较。结果表明,以水为溶剂,收率较高,反应时间较短。关键词:苯,水,绿色化学。
