Abstract
In this research synthesized amino is derivative of Schiff-bases by using electrolysis cell. Electrochemical reduction of para-nitroaniline and electrocatalysed condensation have been carried out at zinc electrode and anode from coal in the presence of potassium chloride as supporting electrolyte in water/methanol solution, and in the application of 20V voltage, where interaction is in two stages: the first stage involves the electrochemical reduction of nitro group and get the amino and the second phase also, azo Schiff was synthesized between para-nitroaniline and metoxybenzealdehyde by electrolysis method, which was supplied with a zinc electrode as cathode to perform electrochemical reduction in the medium of methanol and sodium hydroxide and in the application of 9.5V voltage, the reaction was carried out in two phases. The first stage included condensation to form the Schiff bases, the second stage included electrical coupling, in both cases the reaction monitoring by TLC plates was found that the time needed to complete the reaction was three hours and with a high yield of 98%. The identity of the product was confirmed by available spectroscopic techniques.
