Özet:

 

In this research, the electrochemical oxidation of Mn(II)  acetate to Mn(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   Mn(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 (10% H2O, 90% CH3COOH, 0.1 M   Mn(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 (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   Mn(III) acetate.
