Ukusetshenziswa
I-2-bromo-4-chloropropiophenone ingasetshenziswa njengendawo emaphakathi ku-organic synthesis, ikakhulukazi esetshenziswa ocwaningweni lwaselabhorethri nokuthuthukiswa kanye nezinqubo zokukhiqiza amakhemikhali.
Isixazululo esingu-15.9 g (0.1 mol) we-bromine ku-20 ml we-chloroform yengezwa ngokudonsela phansi kwisixazululo esingu-16.8 g (0.1 mol) se-4'-chloropropiophenone ku-100 ml we-chloroform, phambi kwenani elincane le-aluminium chloride. , futhi ingxube inyakaziswa ubusuku bonke.Ngemva kokuhlunga kanye nokuhwamuka kwe-filtrate, insalela ye-crystalline igezwa nge-petroleum ether.Uma yomile, iyancibilika ku-75° C.
