摘　　要：氯苯硝化反应是强放热反应,放热过程易导致局部热失控迅速升温而引发爆炸。微通道连续硝化工艺是近年来出现的一种相对安全的反应工艺,但其安全性研究还不够全面。为了能够针对性地对该类工艺进行危险分析,综合ETA和HAZOP方法对氯苯在微通道中连续硝化的生产工艺的危险性进行分析。该联合方法能够互补分析缺陷,在微通道连续硝化反应工艺的安全分析中更为适用,对制定安全措施、提高生产安全性具有一定意义。The nitration of chlorobenzene is a strong exothermic reaction,which can easily lead to local thermal run away and rapid heating,leading to explosions.The microchannel continuous nitrification process is a relatively safe reaction process that has emerged in recent years,but its safety research is not comprehensive enough.In order to con duct targeted hazard analysis of this type of process,the paper combines ETA and HAZOP methods to analyze the ha zards of the production process of chlorobenzene continuous nitrification in microchannels.This joint method can complement the analysis of defects and is more applicable in the safety analysis of microchannel continuous nitrifica tion reaction processes,and it has certain significance for formulating safety measures to improve production safety.
