Isingeniso
I-2-Bromo-5-(trifluoromethyl)pyridine (eyaziwa nangokuthi i-BTFP) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: Okuqinile okumhlophe
Isisindo samangqamuzana: 206.00 g/mol
- Ukunyibilika: I-BTFP incibilika kalula kuzincibilikisi zemvelo (isb., utshwala, ama-ether, ama-ketone) kodwa ayincibiliki kancane emanzini.
Sebenzisa:
- Njengokuhlanganiswa okuphakathi: I-BTFP isetshenziswa kabanzi ekulungiseleleni ama-organic synthesis intermediates, njengama-pyridine compounds, ama-aromatics, njll.
- Njenge-ligand: I-BTFP ingasetshenziswa njenge-ligand yezakhiwo zensimbi futhi ihileleke ekuphenduleni okuhlukahlukene kwe-catalytic kanye nokulungiswa kwezinto zokusebenza.
- Njenge-reagent: I-BTFP idlala indima ebalulekile ku-organic synthesis, njengokusabela kokuhlanganisa, ukusabela kokushintshanisa, nokusabela kokunciphisa.
Indlela:
I-2-Bromo-5-(trifluoromethyl)pyridine ingahlanganiswa ngezinyathelo ezilandelayo:
1. Chaza i-2-amino-5-(trifluoromethyl)pyridine ku-solvent yemvelo efanelekile, njengotshwala noma i-ketone.
2. Engeza izinhlanganisela ze-bromine (isb i-hydrogen bromide, i-methyl bromide).
3. Yenza ukusabela ezingeni lokushisa elifanele kanye nezimo ezinyakazayo.
4. Hlunga umkhiqizo futhi wenze i-crystallization kanye nokuhlanza.
Ulwazi Lokuphepha:
- I-BTFP ingase iqine noma icwebezele emazingeni okushisa aphansi, sicela uyigcine ekamelweni lokushisa futhi ugweme ukucwebezela.
- Gqoka amagilavu okuzivikela afanelekile kanye nezibuko ngesikhathi sokusebenza ukuze ugweme ukuthintana nesikhumba namehlo.
- Gwema ukuhogela uthuli noma umhwamuko wayo, njengoba i-BTFP ingase ibe nomthelela ocasulayo emgudwini wokuphefumula.
- Bheka imanuwali efanele yokuphepha lapho usebenzisa noma uphatha i-BTFP, futhi ulahle imfucuza nezincibilikisi ngendlela efanele.
