Abstract :In this research, the electrochemical oxidation of Mninsert ignore into journalissuearticles values(II); acetate to Mninsert ignore into journalissuearticles values(III); acetate was investigated in aqueous acetic acid solution, using a bipolar particulate electrode cell. In order to determine the effect of flow modes on the yield of Mninsert ignore into journalissuearticles values(III); acetate, which is an important oxidizing agent and catalyst in organic reactions, a bipolar particulate electrode cell was employed both in flooded and trickle flow modes. The experiments were conducted at controlled potentials of 50-250 volts using the solution insert ignore into journalissuearticles values(10% H2O, 90% CH3COOH, 0.1 M Mninsert ignore into journalissuearticles values(CH3COO);2.4H2O, 0.1 M CH3COONa.3H2O); and at an optimum flow rate of 0.04 ml.s-1. The values of space-time yields for both electrode cells gave a maximum at about the same voltage range insert ignore into journalissuearticles values(4.5-5 V/number of layer);. The maximum values obtained with approximately identical energy consumption values were 36.13 kg.m-3.h-1 and 23.73 kg.m-3.h-1 in a bipolar packed-bed and trickle-bed electrode cell, respectively. Thus, the effectiveness of the flow modes using a bipolar particulate electrode cell has been demonstrated for the electrosynthesis of Mninsert ignore into journalissuearticles values(III); acetate.
