用途有機合成原料。
使用4'-Bromoacetophenone is an important organic synthesis intermediate, widely used in synthetic medicine, pesticides, dyes, flavors and fragrances, perfumes, Intermediates of Liquid Crystals etc.
製造方法4'-Bromoacetophenone is synthesized by the reaction of bromobenzene and acetic anhydride in the presence of aluminum trichloride. Add bromobenzene and dry carbon disulfide into the reactor, put in powdered anhydrous aluminum trichloride, heat until it starts to reflux, stop heating, add acetic anhydride dropwise, and then reflux for 1 hour after adding, steam out carbon disulfide, and put it while it is still hot. The reactant was poured into the hydrochloric acid ice-water mixture, filtered to dryness, and distilled under reduced pressure to obtain p-bromoacetophenone.
純化方法Crystallise it from EtOH, MeOH or from pet ether (b 80-100o). [Tanner J Org Chem 52 2142 1987, Beilstein 7 IV 647.]
