Intshayelelo
I-2-Bromo-5- (trifluoromethyl) pyridine (eyaziwa ngokuba yi-BTFP) yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: Okuqinileyo okumhlophe
- Ubunzima bemolekyuli: 206.00 g / mol
- Ukunyibilika: I-BTFP inyibilika ngokulula kwizinyibilikisi zendalo (umzekelo, iialkoholi, iietha, iiketones) kodwa ayinyibiliki kancinci emanzini.
Sebenzisa:
- Njenge-synthesis intermediate: I-BTFP isetyenziswa ngokubanzi ekulungiseleleni i-organic synthesis intermediates, efana ne-pyridine compounds, i-aromatics compounds, njl.
- Njenge-ligand: I-BTFP ingasetyenziselwa njenge-ligand yezakhiwo zetsimbi kwaye ibandakanyeka kwiimpendulo ezahlukeneyo ze-catalytic kunye nokulungiswa kwezinto zokusebenza.
- Njenge-reagent: I-BTFP idlala indima ebalulekileyo kwi-organic synthesis, njenge-coupling reaction, i-substitution reaction, kunye nokunciphisa ukusabela.
Indlela:
I-2-Bromo-5-(trifluoromethyl)pyridine inokwenziwa ngala manyathelo alandelayo:
1. Dissolve 2-amino-5-(trifluoromethyl)pyridine kwi-solvent efanelekileyo yezinto eziphilayo, ezifana notywala okanye i-ketone.
2. Yongeza iikhompawundi zebromine (umz. i-hydrogen bromide, i-methyl bromide).
3. Yenza impendulo kwiqondo lokushisa elifanelekileyo kunye neemeko ezishukumisayo.
4. Hlunga imveliso kwaye wenze i-crystallization kunye nokucoca.
Ulwazi ngoKhuseleko:
-I-BTFP inokuqinisa okanye ikhanye kumaqondo obushushu aphantsi, nceda ugcine kwiqondo lokushisa kwaye ugweme i-crystallization.
-Nxiba iiglavu ezifanelekileyo kunye neeglasi ngexesha lokusebenza ukunqanda ukudibana nolusu kunye namehlo.
- Gwema ukuphefumula uthuli okanye umphunga, njengoko i-BTFP ingaba nefuthe elicaphukisayo kwindlela yokuphefumula.
- Jonga kwincwadana yokhuseleko efanelekileyo xa usebenzisa okanye uphethe i-BTFP, kwaye ulahle inkunkuma kunye nezinyibilikisi ngokufanelekileyo.
