3-(2-Chloro-4-trifluoromethylphenoxy)benzoic acid

3-(2-Chloro-4-(trifluoromethyl)phenoxy)benzoic acid can be used in the optimisation study of the aromatic nitration reaction process. Taking the nitration of 3-(2-Chloro-4-(trifluoromethyl)phenoxy)benzoic acid as an example, a continuous-flow mixed-acid aromatic nitration process was developed within a droplet-type microreactor. The effects of key operating parameters were systematically characterised. This process lays the foundation for subsequent production of acifluorfen.
