General Description

3-(2-chloro-4-trifluoromethylphenoxy)benzoic acid is a chemical compound with a molecular formula of C14H8ClF3O3. It is a benzoic acid derivative with a phenoxy group attached to the benzoic acid core. The compound is commonly used as an herbicide and plant growth regulator, primarily to control broadleaf weeds in agricultural and horticultural crops. It works by interfering with the plant's growth hormones, which ultimately leads to the death of the target plants. The compound is a selective herbicide, meaning it targets specific types of plants while leaving others unaffected, and it is often used in combination with other herbicides to achieve a broader spectrum of weed control.

Preparation method of 3-(2-chorine-4-trifluoromethyl) phenoxybenzoic acid

The invention provides a preparation method of 3-(2-chorine-4-trifluoromethyl) phenoxybenzoic acid, and belongs to the field of chemical synthesis. The preparation method has the advantages that the synthesizing process is free from impurities, so that the yield and the purity of a target product can be improved, and solid wastes are decreased. The preparation method is characterized in that m-hydroxybenzoic acid and sodium hydroxide are subjected to refluxing dehydrating in a solvent, and then a catalyst and 2-nitryl-4-trifluoromethyl chlorobenzene are added to react to obtain an intermediate 3-(2-nitryl-4-trifluoromethyl) phenoxybenzoic acid; the intermediate 3-(2-nitryl-4-trifluoromethyl) phenoxybenzoic acid is subjected to hydrogenation reduction and diazotization to obtain the target product 3-(2-chorine-4-trifluoromethyl) phenoxybenzoic acid. By virtue of the preparation method, three-position isomer is completely avoided; the raw materials are low in price and easy to obtain; the preparation method is easily industrially carried out.
