1-Bromo-2,4,5-trifluorobenzene Use and Manufacturing
To a 500-mL three-necked flask, 100 g of 1, 2, 4-trifluorobenzene and 3 g of tin tetrachloride-polystyrene composite were added. Glacial acetic acid was used as a reaction solvent. 127 mL of liquid bromine was slowly added dropwise at room temperature. Reaction 2h, TLC monitoring raw material reaction is complete, vacuum evaporate glacial acetic acid, add 500mL of chloroform, and then wash the organic phase with a concentration of 3percent diluted hydrochloric acid, add saturated sodium sulfite solution to remove the bromine in the organic phase, and wash sequentially, After washing with saturated saline and distilling off the solvent, 158 g of the product, trifluorobromobenzene, was obtained in a yield of 98.7percent, and the purity by gas chromatography was 99.6percent.
