Intshayelelo
1-Bromo-3,3,3-trifluoroacetone. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwale khompawundi:
Umgangatho:
I-1-Bromo-3,3,3-trifluoroacetone ilulwelo olungenambala kunye nephunga elimnandi elikhethekileyo kwiqondo lokushisa kunye noxinzelelo. Iyanyibilika kwii-alcohols, ii-ethers, kunye nezinye izinyibilikisi eziphilayo, kwaye ayinyibiliki emanzini. Ikhompawundi inoxinzelelo oluphezulu lomphunga kunye nokuguquguquka.
Sebenzisa:
I-1-Bromo-3,3,3-trifluoroacetone inoluhlu olubanzi lwezicelo kwishishini lemichiza. Olunye lolona setyenziso luphambili lunjenge-synthetic intermediate ye-fluoroacetone. Ikwasetyenziswa njenge-catalyst ye-organic synthesis kunye ne-surfactant.
Indlela:
I-synthesis ye-1-bromo-3,3,3-trifluoroacetone idla ngokuqhutyelwa ngendlela ye-bromohydrofluoric acid. I-acetone iphendulwa nge-hydrofluoric acid kwi-reactor ukufumana i-bromoacetone. Emva koko, i-bromide ye-sodium yongezwa kumxube wokuphendula, kwaye i-bromination reaction yaqhutyelwa ukufumana i-1-bromo-3,3,3-trifluoroacetone. Imveliso ekujoliswe kuyo ifunyenwe nge-distillation kunye nokucoca.
Ulwazi ngoKhuseleko:
I-1-Bromo-3,3,3-trifluoroacetone iyacaphukisa kwaye inokuba nemiphumo ephazamisayo emehlweni, ulusu kunye nenkqubo yokuphefumla. Xa usebenzisa, kufuneka kuthathwe amanyathelo afanelekileyo okuzikhusela afana namehlo akhuselayo, iiglavu kunye neziphefumla. Kufuneka isetyenziswe kwindawo engena umoya kwaye ugweme ukudibana nezinto ezinjengee-oxidants ezinamandla.
