【摘要】 采用无隔膜电解槽，以ＰｂＯ２／Ｔｉ为阳极，纯Ｐｂ为阴极，将锰（Ⅱ）在电解槽中氧化为锰（Ⅲ），以锰（Ⅲ）为氧化媒质，采用槽外间接电氧化法将２，４－二氯甲苯氧化成２，４－二氯苯甲醛。用优选法选择了氧化的最佳温度。更多还原

【Abstract】 The process adopted non-membrane electrolytic cell,took the PbO2/Ti made by self as the anode,pure Pb plate as the cathode respectively.The author electrolyzes MnSO4 to Mn(Ⅲ) in the medium of H2SO4 under proper conditions.Then,in the outside cell,use Mn(Ⅲ) to oxidize 2,4-dichlorobenzene to form 2,4-dichlorobenzaldehyde.更多还原
