| | 4-Bromo-3-chlorophenol Usage And Synthesis |
| Uses | 4-Bromo-3-chlorophenol is used as a precursor in organic synthesis to prepare 4-(benzyloxy)-l-bromo-2-chlorobenzene by reaction with benzyl bromide. | | Synthesis |
45.7 g (0.466 mol) of 3-chlorophenol and 80 mL of carbon tetrachloride were added into a four-necked flask, and 82.74 g (0.465 mol) of NBS was added in batches under stirring, and the reaction was carried out at a certain temperature temperature, and the samples were taken every 2 h, and analyzed by gas chromatography, and the reaction was stopped when the mass fraction of 3-chlorophenol was less than 1 %. Filtering, the filtrate was washed with water, the oil layer was taken for distillation, and the 37-38 / 0.000 4 MPa fraction was collected as the 4-bromo-3-chlorophenol product, the purity of which was greater than 98% (GC), with a yield of 87%.
