Syntheses of di-Schiff’s bases: A comparative study using benzene and water (concept of green chemistry) as solvents

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.
