overview 3-trifluoromethylbenzoic acid is a chemical intermediate of medicine and pesticide, which is widely used in medicine, pesticide and other fields. At present, there are mainly the following preparation methods: 1) using m-difluorotoluene as raw material, heating and reflux hydrolysis with 30% fuming sulfuric acid, cooling and adding to ice water, filtering to obtain the product with a yield of 66.1%. The preparation method has a low yield and produces a large amount of waste acid, which does not meet the requirements of green production. 2) Using meta-trifluoromethyl chloride as raw material, first chlorinated with chlorine under the action of an initiator at 50-90 ℃, and then refluxed with 2.5-10% sodium hydroxide for hydrolysis, neutralization and filtration to obtain inter-product trifluoromethyl benzoic acid, the two-step total yield is 76.5-85.5%. The chlorine gas used in the preparation method will be greatly restricted in actual use, and it is a two-step reaction, and the total yield is not very high.
preparation add 100g of intermediate-(trifluoromethyl) benzyl chloride and 0.5g of initiator azodiisoheptonitrile in a 250ml three-mouth flask, raise the temperature to 70 ℃, start to introduce dry chlorine gas, control the chlorine passing temperature to be kept between 70-75 ℃, finish the chlorine passing when the specific gravity of the reaction solution reaches 1.48-1.50, and remove the residual chlorine, it was steamed out at 53-55 ℃ under a reduced-pressure 2mmHg column (German Patent DE2548970(1997) reported that under a reduced-pressure 11mmHg column, bp87 ℃), and 127g of 1-(trichloromethyl)-3-(trifluoromethyl) benzene with a content of 96.9% was obtained, with a yield of 91.8%. Then 50g of prepared 1-(trichloromethyl)-3-(trifluoromethyl) benzene and 1600g of 2.5% NaOH aqueous solution are put into a 3000ml three-mouth flask, heated and refluxed for 12 hours, neutralized the pH of the reaction solution with 10% hydrochloric acid to 4, precipitated by white precipitate, filtered by suction, washed with a small amount of water, and dried by vacuum at 60 ℃ for 10 hours to obtain 32.4g of crude white powdered m-(trifluoromethyl) benzoic acid, the content is 97.3%, the melting point is 103-104 ℃, and the reaction yield is 88.6%. After recrystallization of the crude product by CCl4, the melting point is 105.2-105.5 ℃, and the melting point of m-(trifluoromethyl) benzoic acid with 99% purity is 105-106 ℃.
