摘　　要：以某公司氟磺胺草醚的硝化中间体为例,原生产硝化工艺为釜式间歇反应工艺,由于釜式硝化反应不易实现连续化,反应时间长,物料在线量大,生产过程强放热,反应热不易移出体系外,易造成超温反应,促进二硝基物、多硝基物等副产物的生成,釜内压力升高,从而引发爆炸、火灾事故的发生。为了提高本质安全度水平,积极实施硝化新工艺改进,有效降低安全风险,对氟磺胺草醚采用微通道反应器连续硝化生产工艺,进一步提升工艺本质安全水平,管控源头风险。Taking the nitration intermediate of fomesafen in a certain company as an example,the original production nitration process was a kettle batch reaction process.Due to the difficulty in continuity,long reaction time,large online quantity of materials,strong exothermic production process,and difficulty in removing reaction heat from the system,kettle type nitrification reaction is prone to overheating reactions and the generation of by-products such as dinitride and polynitro compounds,the rising pressure inside the kettle,leading to the occurrence of explosive and fire accidents.To improve the intrinsic safety level,we implement the spirit of relevant documents issued by national ministries and provincial departments,actively implement the improvement of new nitrification processes,effectively reduce safety risks,adopt a continuous nitrification production process of fomesafen by using microchannel reactor,further enhancing the intrinsic safety level of the process and controlling the source risk.
