Intshayelelo
I-Tetraphenylphosphine bromide yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-tetraphenylphosphine bromide:
Umgangatho:
- I-Tetraphenylphosphine bromide yikristale engenambala okanye umgubo omhlophe oqinileyo.
-Inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethers kunye ne-chlorinated hydrocarbons, enganyibilikiyo emanzini.
- Sisiseko esomeleleyo seLewis esinokwenza iikhompleksi ezineentsimbi ezininzi.
Sebenzisa:
- I-Tetraphenylphosphine bromide isetyenziswa ngokubanzi njenge-reagent yekhemikhali kwi-organic synthesis.
- Ingasetyenziswa njenge-ligand yensimbi yenguqu kwaye ibandakanyeka kwiimpendulo ze-catalytic.
- Isetyenziswa ngokuqhelekileyo kwi-organic synthesis yokongeza i-carbonyl compounds kunye ne-carboxylic acids, kunye ne-amination reaction kunye ne-conjugate add of olefins.
Indlela:
- I-Tetraphenylphosphine bromide inokulungiswa ngokuphendula i-tetraphenylphosphine kunye ne-hydrogen bromide.
- Ngokuqhelekileyo isabela kwizinyibilikisi eziphilayo ezifana ne-ether okanye i-toluene.
- Isiphumo se-tetraphenylphosphine bromide sinokucwebezela ngakumbi ukuvelisa imveliso esulungekileyo.
Ulwazi ngoKhuseleko:
- I-Tetraphenylphosphine bromide iyacaphukisa ulusu kunye namehlo kwaye kufuneka igwenywe ngokudibana ngokuthe ngqo.
- Sebenzisa kwindawo engenamoya kwaye unxibe izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu kunye neendondo.
- Qaphela ukuba inokuvelisa umsi oyityhefu kunye neegesi ezidliwayo xa ishushu kwaye ibola.
- Xa ugcina, kufuneka ugcinwe kude nomlilo kunye ne-oxidants, kwaye ugweme ukudibanisa ne-oxygen.
- Ukuba utyiwe okanye uphefumle, funa unyango ngokukhawuleza.
