Isingeniso
1-Bromo-3,3,3-trifluoroacetone. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwale nhlanganisela:
Ikhwalithi:
I-1-Bromo-3,3,3-trifluoroacetone iwuketshezi olungenambala olunephunga elimnandi elikhethekile ekamelweni lokushisa nokucindezela. Iyancibilika kuma-alcohols, ethers, nakwezinye izinyibilikisi eziphilayo, futhi ayincibiliki emanzini. I-compound inomfutho we-vapor ophezulu kanye nokuguquguquka.
Sebenzisa:
I-1-Bromo-3,3,3-trifluoroacetone inohlu olubanzi lwezinhlelo zokusebenza embonini yamakhemikhali. Enye yezinto ezisetshenziswa kakhulu njenge-synthetic intermediate ye-fluoroacetone. Ibuye isetshenziswe njenge-catalyst ye-organic synthesis nanjenge-surfactant.
Indlela:
Ukuhlanganiswa kwe-1-bromo-3,3,3-trifluoroacetone ngokuvamile kwenziwa ngendlela ye-bromohydrofluoric acid. I-acetone isabela nge-hydrofluoric acid ku-reactor ukuthola i-bromoacetone. Khona-ke, i-sodium bromide yanezelwa engxubeni yokusabela, futhi ukusabela kwe-bromination kwenziwa ukuze kutholakale i-1-bromo-3,3,3-trifluoroacetone. Umkhiqizo ohlosiwe utholakala nge-distillation nokuhlanza.
Ulwazi Lokuphepha:
I-1-Bromo-3,3,3-trifluoroacetone iyacasula futhi ingase ibe nemiphumela ecasulayo emehlweni, esikhumbeni, nasesistimu yokuphefumula. Lapho usebenzisa, kufanele kuthathwe izinyathelo ezifanele zokuzivikela ezifana nezingubo zamehlo ezivikelayo, amagilavu, nezinsimbi zokuphefumula. Kufanele isetshenziswe endaweni enomoya omuhle futhi igweme ukuthintana nezinto ezifana nama-oxidants aqinile.
