Isingeniso
I-2-Fluoro-3-chloro-5-bromopyridine iyinhlanganisela yezinto eziphilayo.
Inhlanganisela iqinile ngokubukeka kwekristalu okumhlophe kuya kokuphuzi ngokukhanyayo. Ayincibiliki emanzini ekamelweni lokushisa, kodwa ingancibilika kwezinye izincibilikisi eziphilayo njenge-methanol ne-methylene chloride.
I-3-Bromo-5-chloro-6-fluoropyridine inenani elithile lohlelo lokusebenza ku-organic synthesis. Ivamise ukusetshenziswa njengendawo emaphakathi yokusabela okuhlukahlukene ku-organic synthesis, njengokusabela kokuhlanganisa kanye nokusabela okunephunga elimnandi kwe-hydrocarbon. Lokhu kusabela kungadlala indima ebalulekile ekwakhiweni kwezinhlaka eziyinkimbinkimbi zamangqamuzana ezinto eziphilayo.
Indlela yokulungiselela i-3-bromo-5-chloro-6-fluoropyridine ingenziwa ngezindlela ezihlukahlukene. Indlela evamile iwukwenza ukusabela kwe-halogenation okuzinyathelo ngezinyathelo kusetshenziswa izingxenye ezihambisanayo ze-pyridine, okokuqala wethula i-fluorine endaweni yesi-3, bese i-chlorine endaweni yesi-5, futhi ekugcineni i-bromine ibe sendaweni yesi-6.
Ulwazi lokuphepha: I-3-Bromo-5-chloro-6-fluoropyridine iyikhemikhali futhi kufanele isingathwe ngokuhambisana nezinqubo zokusebenza zokuphepha ezifanele. Kungase kucasule isikhumba, amehlo, nendlela yokuphefumula, futhi izinto zokuzivikela ezifanele njengamagilavu, izibuko, nezingubo zokuzivikela kufanele zigqokwe lapho usebenza.
Ukugcinwa nokuphathwa kwamakhemikhali kufanele futhi kwenziwe ngokuhambisana nemithethonqubo efanele, futhi kuhlukaniswe futhi kubhalwe ngokuhambisana nezakhiwo ezibonakalayo zamakhemikhali. Lapho usetshenziswa, qinisekisa ukungena komoya ngendlela efanele futhi ugweme ukuhogela amagesi noma umhwamuko.
