摘要
对硫酸钴（Ⅲ）电化学制备以及用其作氧化媒质合成邻硝基苯甲醛进行了研究。结果表明，在１１℃、以银离子作催化剂，用Ｐｂｏ＿２／Ｐｂ作阳极，在含０．４５ＭＣＯＳＯ＿４的５．３Ｍ硫酸溶液中进行电解反应时，可获得较高的电流效率。在温度１２℃，９．２Ｍ硫酸溶液中，使用过量７０倍的邻硝基甲苯进行化学合成时，邻硝基苯甲醛的收率达７４．５％。
he electrochemical preparation of cobaltic sulphate and chemical synthesis of o- nitroben-zaldehyde using cobaltic sulphate as oxidant have been studied.The results show that the highest current effi-ciency of the electrolytic reaction is obtained in a solution consisting of 0.45M CoSO_4 and 5.3M H_2SO_4 us-ing silver ions as the catalyst,PbO_2/Pb as the anode at 11℃. When the chemical reaction was carried outin the system of dispersing 7 0 times excess of o- nitrotoluene in a solution of cobaltic sulphate in 9. 3MH_2SO_4 at 12℃,the yield of o-nitrobenzaldehyde reached 7 4.5%.
