Isingeniso
I-5-Bromo-2-fluoropyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
Ukubukeka: I-5-bromo-2-fluoropyridine iqinile engenambala ukuya kokuphuzi okukhanyayo.
Ukunyibilika: Incibilika kuzincibilikisi zemvelo njenge-ethanol, i-dimethylformamide (DMF) ne-dichloromethane.
Sebenzisa:
I-Chemical synthesis: I-5-bromo-2-fluoropyridine ingasetshenziswa njengendawo ephakathi ku-organic synthesis futhi idlala indima ebalulekile ekulungiseleleni ezinye izinhlanganisela eziphilayo.
Indlela:
Ngokuvamile, indlela yokulungiselela i-5-bromo-2-fluoropyridine iqukethe izinyathelo ezilandelayo:
I-Pyridine isabela ne-hydrogen fluoride ukunikeza i-2-fluoropyridine.
I-2-Fluoropyridine isabela nge-bromine ngaphansi kwezimo ze-alkaline ukuze ithole i-5-bromo-2-fluoropyridine.
Ulwazi Lokuphepha:
Ukuphepha: I-5-Bromo-2-fluoropyridine ingaba yingozi empilweni nasemvelweni, futhi izinqubo ezifanele zokusebenza zokuphepha kufanele zilandelwe. Ukuxhumana okuqondile nesikhumba namehlo kufanele kugwenywe ngesikhathi sokusetshenziswa, futhi umoya omuhle kufanele uqinisekiswe.
Isitoreji: I-5-Bromo-2-fluoropyridine kufanele igcinwe esitsheni esingangeni moya, kude nomlilo nezinto ezivuthayo.
Ukulahlwa kukadoti: Ngokwemithetho yendawo, imfucuza engu-5-bromo-2-fluoropyridine kufanele ilahlwe ngendlela efanele ngokuhambisana nemithethonqubo efanele.
