Acifluorfene Molecular Formula


Synonyms: Acifluorofen; 2-Nitro-5-(2-chloro-4-(trifluoromethyl)phenoxy)benzoic acid; 5-[2-Chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid; Carbofluorfen; PPG-847; 5-(2-chloro-α,α,α-trifluoro-p-tolyloxy)-2-nitrobenzoic acid; Acifluorfen



It is a post selective herbicide, which can be used in the early treatment of seedling, and can be absorbed by weeds, stems and leaves. Is the original porphyrin oxidase inhibitor. The drug is absorbed by the weed stem and leaves, and inhibits the mitochondrial electron conduction, causing the respiratory system and the energy production system to arrest and inhibit the cell division and make the weeds die. Apply to other weed control of annual broadleaf weeds and soybean, peanut and other crops such as purslane, Commelina communis, Acalypha australis L., Abutilon theophrasti medic, Carpetweed, Chenopodium album, Solanum nigrum, Xanthium sibiricum, Datura and other. The recommended dosage of soybean is 380 ~ 420g/hm2, and the rice field is 180 ~ 320g/hm2. For example, the use of soybean, generally in the 1 ~ 3 leaves of soybean, weeds 2 to 4 leaves, with 24% 7.5mL/100m2 water (such as drought and weeds from 3 to 4 leaves of 11.3mL), the water spray weed stems and leaves. Do not mix with fertilizer.

 

Production method

1. inter-hydroxy acid as raw materials

Equimolar 3,4 dichlorobenzotrifluoride and m-hydroxybenzoic acid, in the presence of KOH in DMSO as solvent, the reaction at 138 ~ 144 ℃ 22h, to yield 3- (2-chloro-4 - trifluoromethylphenoxy) benzoic acid. Then in dichloromethane solvent using potassium nitrate - sulfuric acid nitration reaction of acifluorfen. And then reacted with an equimolar NaOH to form the sodium salt.

2. cresol as raw material

Equimolar 3,4 dichlorobenzotrifluoride and m-cresol potassium salt, at 149 ~ 155 ℃ in a solvent, to yield 3- (2-chloro-4-trifluoromethyl-phenoxy) methyl benzene, and in the catalyst, the presence of acetic acid, at 94 ~ 96 ℃ through air oxidation, to give 3- (2-chloro-2-trifluoromethylphenoxy) benzoic acid, then mixed with an acid in a solvent and vinegar bar presence at 45 ℃ nitration acifluorfen, then reacted with an equimolar NaOH to form the sodium salt.

3-chloro-4-hydroxy-trifluoromethylphenyl as raw material

Equimolar 3-chloro-4-hydroxy-trifluoromethylphenyl with 5-chloro-2-nitrobenzoic acid in the solvent DMSO, potassium and nitrogen, at room temperature to produce acifluorfen.
