Synthesis of N benzylidene aniline by green chemistry

Abstract

Green chemistry provides a solvent free organic synthesis without raising the temperature in order to respect the environment. In this work this new discipline has been adopted to synthesize an imine called Schiff base which N Benzylidene Aniline is created by the condensation of aniline on benzaldehyde in the presence of a catalyst at 0.1%. This synthesis was conducted without using solvent, and without raising the temperature as dictated by the method of green chemistry. The mixture of reagents was placed in a mortar in order to exert pressure to synthesize the imine. At a reaction time of 2 min, the yield obtained is 57%. The yellowish solid product was analyzed by infrared spectroscopy, which confirmed the presence of characteristic bands of the azomethine C = N group at 3057 and 1630 nm-1.
