硫酸铈氧化对二甲苯制对甲基苯甲醛

Preparation of p-Toluic- Aldehyde by Using the Oxidation of p-Xylene with Cerium Sulfate

用硫酸铈为媒质间接电氧化对二甲苯制对甲基苯甲醛。在优选的条件下，电氧化Ｃｅ（ＩＶ）的产率≥８５％。采用十二烷基硫酸钠等催化剂可以明显地加速合成对甲基苯甲醛的反应。

The preparation of ptoluic aldehyde by using the indirect electrooxidation of pxylene with cerium sulfate is given in this paper.Under the optimum condition,the yeild of Ce(Ⅳ) is more than 85% in the electrooxidation.The synthesis reaction of ptoluic aldehyde can be accelerated obviously by some catalysts,such as sodium dodecyl sulfate.
