Abstract
A full continuous flow synthesis process of fluorine-containing aromatic hydrocarbon compounds. Aromatic amine and hydrogen fluoride are respectively pumped into thermostats A and B, then flow into micro-channel reactor C for salt forming reaction whose temperature is kept constant; sulfuric acid solution of nitrosylsulfuric acid is pumped into thermostat D; after keeping the temperature constant, the sulfuric acid solution of nitrosylsulfuric acid and salt forming product flowing out from the micro-channel reactor C flow into micro-channel reactor E for diazotization reaction; the obtained product flows into micro-channel reactor F for thermal decomposition reaction, is cooled in cooler G, then enters three-phase separator H for continuous separation, fluorine-containing aromatic hydrocarbon crude product is subjected to continuous alkaline washing, drying and rectification to obtain fluorine-containing aromatic hydrocarbon finished product, and mixture of hydrofluoric acid and sulfuric acid is continuously distilled to obtain hydrogen fluoride and sulfuric acid.
