Isingeniso
I-Tetraphenylphosphine bromide iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-tetraphenylphosphine bromide:
Ikhwalithi:
- I-Tetraphenylphosphine bromide iyikristalu engenambala noma impuphu emhlophe eqinile.
- Ancibilika kuzincibilikisi zemvelo njengama-ether nama-hydrocarbon e-chlorinated, angancibiliki emanzini.
- Isisekelo se-Lewis esiqinile esingakha izakhiwo ezinezinsimbi eziningi.
Sebenzisa:
- I-Tetraphenylphosphine bromide isetshenziswa kabanzi njenge-reagent yamakhemikhali ku-organic synthesis.
- Ingasetshenziswa njenge-transition metal ligand futhi ihileleke ekuphenduleni kwe-catalytic.
- Ivamise ukusetshenziswa ekuhlanganiseni kwe-organic ukuze kwengezwe izinhlanganisela ze-carbonyl nama-carboxylic acid, kanye nokusabela kwe-amination kanye nokwengezwa kwe-conjugate kwama-olefin.
Indlela:
- I-Tetraphenylphosphine bromide ingalungiswa ngokusabela i-tetraphenylphosphine nge-hydrogen bromide.
- Ivamise ukusabela kuzincibilikisi zemvelo njenge-ether noma i-toluene.
- I-tetraphenylphosphine bromide ewumphumela ingaphinda icwebezeliswe ukuze ikhiqize umkhiqizo omsulwa.
Ulwazi Lokuphepha:
- I-Tetraphenylphosphine bromide iyacasula esikhumbeni nasemehlweni futhi kufanele igwenywe lapho uthintana ngqo.
- Sebenzisa endaweni enomoya omuhle futhi ugqoke izinto zokuzivikela ezifanele njengamagilavu nezibuko.
- Qaphela ukuthi ingase ikhiqize intuthu enobuthi namagesi ezonakalisayo lapho ishisa futhi ibola.
- Uma uyigcina, kufanele igcinwe kude nomlilo nama-oxidants, futhi ugweme ukuthintana nomoya-mpilo.
- Uma udliwe noma uhogelwe, funa usizo lwezokwelapha ngokushesha.
