This thesis consists of the study on electrode processes with special reference to compounds of industrial importance. The author’s work is mainly oriented towards the electrochemical synthetic aspect. The electrolytic reaction and their use in organic synthesis are dealt with. An account of fundamentals of electrode kinetics and the factors involved in the application of electrochemical studies and practical process for production of organic compounds have been elaborated. Electro-oxidation of organic compounds has been dealt with. Galvanostatic polarisation measurements have been carried out extensively. The effect of current density, temperature and acid concentration on the yield of the product has been dealt with elaborately. An account of direct oxidation of furfuraldehyde to maleic acid on lead dioxide electrode has been given. Various parameters affecting the current efficiency for the formation of maleic acid are given. Probable oxidation products of furfuraldehyde have been given to explain the lesser yield of maleic acid. The oxidation of p-Xylene to terephthalic acid is given. As there is no good efficiency for the oxidation, two stage processes for the oxidation has been suggested. Chromic acid is used for the chemical oxidation of p-Xylene to terephthalic acid. During the oxidation, chromic acid gets reduced to trivalent chromium. The hexavalent chromium is regenerated by electrolytic oxidation at lead dioxide electrode in sulphuric acid medium. Use of blue asbestos fibre instead of a separate cathode chamber has been found useful in the regeneration process. The electro reduction at dissolving type of cathode and the electro reduction of p-nitrosodimethyl aniline at copper cathodes are elaborated. The dissolution of the metal even under cathodic conditions has been explained on the basis of well known potential pH diagram. The reduction of p-nitro phenol to p-aminophenol is also dealt with. The attack is not much as in the case of p-nitrosodimethyl aniline. The electro reduction of nitro compounds is described. Various factors affecting the current efficiency in the preparation of naphthylamine has been discussed. The preparation of p-aminosalicyclic acid from o-nitro toluene is given. This is a mixture of chemical and electrochemical steps. As other steps are well known in this synthesis emphasis is laid on the electro reduction of p-nitro salicylic acid to p-aminosalicylic acid in the catholite.
