According to the list of high-risk processes published in the "Emergency Notice on Effectively Strengthening Safety Production Work in Chemical Enterprises" by the General Office of the State Council's Work Safety Committee, processes such as nitration, chlorination, fluorination, ammoniation, sulfonation, hydrogenation, diazotization, oxidation, peroxide treatment, cracking, polymerization, etc. are all included.What chemical workers find even more striking than what's mentioned in the document is the stinging odor of toxic gas leaks, coupled with the instantaneous explosion risks from high pressure...As a representative of cutting-edge technology, continuous flow reactors have several improvements over traditional reactors in terms of safety, yield, and more. This article conducts a suitability analysis of some hazardous processes for continuous flow reactors, hoping to utilize these reactors to enhance safety in chemical production processes, so that we are no longer 'afraid of chemistry'.

Phosgene or phosgenation reaction refers to the preparation process of phosgene and the process routes for producing phosgenation products using phosgene as a raw material. Phosgene is a highly toxic gas, and leakage during storage, transportation, and use can easily lead to widespread contamination and poisoning accidents. Moreover, the reaction medium poses a risk of combustion and explosion, and the byproduct hydrochloric acid generated during the reaction is corrosive, which can easily cause equipment and pipeline leaks, leading to poisoning incidents.
