Chemie und Industrie
Verwendung und Herstellung
Anwendungen
Beschreibung4´-Bromacetophenon bildet farblose bis schwach gelbe, wasserunlösliche Kristalle. Die Verbindung besitzt nur wissenschaftliches Interesse.
Verwenden4'-Bromoacetophenone is an important organic synthesis intermediate, widely used in synthetic medicine, pesticides, dyes, flavors and fragrances, perfumes, Intermediates of Liquid Crystals etc.
Darstellung
synthetische4'-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.
