| titleOfInvention | A kind of method for preparing 3-fluorotrifluorotoluene based on dinitrogen trioxide diazotization |
| abstract | The invention discloses a method for preparing 3-fluorotrifluorotoluene based on dinitrogen trioxide diazotization, comprising the following steps: pumping a fluoroboric acid solution and m-aminotrifluorotoluene into a salt-forming microchannel reactor for reaction; The product enters into the diazonium salt tubular reactor and feeds into dinitrogen trioxide for reaction, the product enters into the diazonium salt temporary storage kettle, and then is continuously centrifuged, and the diazonium salt is dried and thermally decomposed; The mother liquor is concentrated, and the waste water produced during the concentration is reused to prepare a fluoroboric acid solution; the gas generated during the thermal decomposition of the diazonium salt is sprayed and absorbed with an acid solution, and the residue generated during the thermal decomposition is used for wastewater treatment; spray absorption After the liquid is layered, the oil layer is pumped into the rectification tower for rectification treatment to obtain the target product, and the water layer is used to prepare a fluoroboric acid solution. The invention recycles and utilizes both waste liquid and solid waste in production, effectively saves resources, and has high product yield and high purity. |
