    Ukusetyenziswa

    I-2-bromo-4-chloropropiophenone ingasetyenziselwa njengendawo ephakathi kwi-organic synthesis, esetyenziswa kakhulu kuphando lwebhubhoratri kunye nophuhliso kunye neenkqubo zokuvelisa imichiza.

    Isisombululo se-15.9 g (0.1 mol) ye-bromine kwi-20 ml ye-chloroform yongezwa nge-dropwise kwisisombululo se-16.8 g (0.1 mol) ye-4'-chloropropiophenone kwi-100 ml ye-chloroform, phambi kwexabiso elincinci le-aluminium chloride. , kwaye umxube uxutywe ubusuku bonke.Emva kokucoca kunye nokunyuka kwe-evaporation ye-filtrate, i-residu ye-crystalline ihlanjwe nge-petroleum ether.Xa yomile, inyibilika kuma-75° C.
