【摘要】 在分隔型电解槽中，用Ｐｂ／ＰｂＯ２阳极将Ｃｒ(３＋)氧化成为Ｃｒ２Ｏ７(2-)；探讨了浓度、电流密度、温度等对电流效率的影响。在所推荐的条件下，阳极电流效率达到８０％。再以ＣｒＯ７为氧化剂将间硝基甲苯氧化成间硝基苯甲酸。研究表明，该过程具有收率高、产品质量好、污染小等优点。更多还原

【Abstract】 Electro-oxidation of Cr₂（SO₄）₃ on Pb/PbO₂ anode in H₂SO₄ solution was carried out in a dividedcell separated by an anion exchange membrane. The influences of factors, such as the concentration, currentdensity, temperature, etc., were investigated. Under the typical conditions appreciated, the anodic averagecurrent efficiency could reach 80%. The oxidation of m-nitrotoluene with Cr₂O₇^2- was also studied. Resultsshowed that the process employed gave higher yield, better product quality and less pollution.更多还原
