| titleOfInvention | Preparation method of 2-fluoro-4,5-dichloronitrobenzene |
| abstract | The invention discloses a preparation method of 2-fluoro-4,5-dichloronitrobenzene, relating to the technical field of preparation of medicine and pesticide intermediates. The industrialized preparation method of the 2-fluoro-4,5-dichloronitrobenzene comprises the following steps: by using 4-fluoroaniline as an initial raw material, carrying out acetylation, chlorination, hydrolysis, diazotization-Sandmeyer reaction and nitrification to synthesize the 2-fluoro-4,5-dichloronitrobenzene. The 2-fluoro-4,5-dichloronitrobenzene prepared by the method disclosed by the invention is a light yellow solid, and the purity is 98.5%; the raw material conversion rate for each reaction step reaches 100%; and the total yield of the whole process is up to 27.1%. |
