Preparation of 2, 3-Pyrazinedicarboxylic Acid by the Electrolytic Oxidation of Quinoxaline

Abstract

Preparation of 2, 3-pyrazinedicarboxylic acid by electrolytic oxidation of quinoxaline, in the presence of potassium permanganate was studied, using a diaphragm. The most suitable electrode material, optimal concentration of the alkali, amount of permanganate added, electric density, electrolytic temperature, manner of quinoxaline addition, and amount of electricity were determined.
