Use 4-bromobiphenyl is an intermediate of rodenticides bromophoryl and bromadiolone.
intermediates in organic synthesis.
for liquid crystal raw materials and intermediates
production method is obtained from p-bromoaniline by the following reaction. Water, p-bromoaniline and concentrated hydrochloric acid were cooled together, and an aqueous solution of sodium nitrite was slowly added while keeping it at 0-5 ° C., diazotization was carried out until the starch potassium iodide test paper was blue, and a clear diazo solution was filtered out. Benzene was added to the diazo solution, and the mixture was stirred at 5-10 ° C. For half an hour while slowly adding sodium hydroxide solution dropwise. After the addition, the mixture was further stirred for 3H, and then for 45h at room temperature. The benzene layer was separated, washed with water, distilled off, and then distilled under reduced pressure. The 170-175 °c (1.06kPa) fraction was collected and recrystallized from ethanol to obtain a finished product having a melting point of 90 °c.
The preparation method is that biphenyl is dissolved in 85% acetic acid, bromine is added to the solution, and the reaction is stirred at room temperature in the absence of light, then extracted with a solvent, and the solvent is distilled off to obtain a product. 4-bromobiphenyl can also be obtained by gas-solid reaction of biphenyl with bromine in the presence of β-dextrin.
