摘要
采用Ｐｂ－ＰｂＯ２阳极，常温下电解含有硫酸铵的酸性硫酸锰电解液，电生氧化媒质Ｍｎ３＋，进而在ＰＴＣ存在下氧化对二甲苯为Ｐ—甲基苯甲醛．探讨了制备电生氧化媒质的优选条件，以及不同的ＰＴＣ及氧化反应温度对Ｐ—甲基苯甲醛产率的影响．还原后的Ｍｎ２＋电解液可以返回电解槽电解再生，实现了循环使用．
This paper reported that the acid manganese sulfate in electrolyte containing ammonium sulfate was electrooxidated on Pb—PbO 2 anode at ordinary temperature to generate Mn 3+ ,and Mn 3+ oxidated p-xylene to producting p-toluic aldehyde in existence of PTC.It was researched that optimal condition of ganerating Mn 3+ ,and the difference PTC and temperature of oxidation reaction in fluencing product yield of p-toluic aldehyde. The generated Mn 2+ electrolyte in process of oxidate reaction to preparating.p-toluic aldehyde can be electrolyzed to regenerate Mn 3+ and used cyclely.
