摘要
对硫醇氧化为二硫化物的反应作了讨论，并在此基础上选择出一种符合二甲硫基甲苯二胺合成体系工艺要求的甲硫醇回收方法。以小试得出的最佳反应条件已在中试工艺中实施，效果良好。
The methods of oxidizing mercaptan into organic bisulfide are simply discussed. On the basis of this, a recovery method suitable for the technical demand of dimethylthio toluene diamine synthesis system was selected. The optimum reaction condition obtained in lab was carried out in pilotplant. The effect is good.
