摘　　要：介绍促进剂M的生产工艺技术以及生产过程中"三废"的产生和处理方法。促进剂M的主要生产方法为以苯胺为原料的高压合成法:苯胺法(间歇法)和苯胺/硝基苯法(连续法),2种方法的收率分别约为85%和89%。促进剂M生产过程中产生的废气硫化氢可制成硫酸或液态硫;废渣目前用作混凝土添加剂或用于防水卷材,今后向制作热塑性树脂和硫化剂发展;废水经电解氧化预处理与生化处理后达标排放。The production technology of accelerator M and the waste treatment processes are introduced. The main production technology is high pressure synthesis by using aniline as the raw material, including the batch aniline process and continuous aniline/nitrobenzene process, which have the production yields of approximately 85% and 89%, respectively. The waste hydrogen sulfide generated by the production process can be used to produce sulfuric acid or liquid sulfur. The solid waste is currently used as additive in concrete and waterproofing membrane, and is under development to produce thermoplastic resin and cross-linking agent. The wastewater is pretreated by electrolytic oxidation process and then treated by a biochemical process to meet the discharge standards.
