Abstract :Cobaltinsert ignore into journalissuearticles values(III); acetate, which is an important oxidizing agent and catalyst in organic reactions, was electrosynthesized from cobaltinsert ignore into journalissuearticles values(II); acetate solution in a bipolar packed-bed flow reactor. In order to determine the effect of the number of layers on the yield of cobaltinsert ignore into journalissuearticles values(III); acetate, experiments were performed in three different lengths of bipolar electrode cells, namely 16, 29 and 55 layers of graphite Raschig rings. The experiments were carried out at controlled potentials of 50-450 V, measuring the total current and using the solution insert ignore into journalissuearticles values(5% H2O, 95% CH3COOH, 0.06MCoinsert ignore into journalissuearticles values(CH3COO);2.4H2O, 0.2M CH3COONa.3H2O); at 298 K and 0.133 L.h-1 flow rate. According to the experimental results, the production of cobaltinsert ignore into journalissuearticles values(III); acetate with the conversion ratio of 43% and the space-time yield of 35.9 kg.m-3.h-1 showed that 29 layers was the optimum.
