Isingeniso
I-2-chloro-3-bromopyridine iyinhlanganisela ephilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Izakhiwo: I-2-Chloro-3-bromopyridine iqinile ngokubukeka kwekristalu emhlophe. Ayincibiliki emanzini ekamelweni lokushisa kodwa incibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ether, nama-hydrocarbon ane-chlorine. Inephunga elimnandi elinamandla.
Ukusetshenziswa: I-2-chloro-3-bromopyridine inenani elibalulekile lesicelo ku-organic synthesis. Ingasetshenziswa futhi ekuhlanganiseni izibulala-zinambuzane, odayi, nezinye izinhlanganisela eziphilayo.
Indlela yokulungiselela: Indlela yokulungiselela ye-2-chloro-3-bromopyridine itholakala ikakhulukazi ngokusabela kwamakhemikhali. Indlela evamile yokulungiselela iwukusabela i-2-bromo-3-chloropyridine nge-reagent efanele njenge-zinc chloride noma i-chloromethyl bromide ukuze uthole umkhiqizo oqondiwe.
Ulwazi Lokuphepha: Njengamakhemikhali amaningi, i-2-chloro-3-bromopyridine idinga ukuphathwa nokugcinwa ngaphansi kwezimo ezifanele zaselabhorethri. Inokucasuka okuthile futhi ingabangela umonakalo esikhunjeni, emehlweni, nasemgudwini wokuphefumula. Izimpahla zokuzivikela ezifanele njengezingilazi zokuphepha, amagilavu, nezinto zokuvikela ukuphefumula kufanele zigqokwe ngesikhathi sokusetshenziswa. Ukuthintana nama-oxidizing agents aqinile namanye amakhemikhali ayingozi kufanele kugwenywe. Uma kwenzeka ukuthintana ngengozi, indawo ethintekile kufanele igezwe ngokushesha futhi kutholakale usizo lwezokwelapha ngokushesha. Imithetho yendawo yendawo kufanele ilandelwe lapho kusingathwa futhi kulahlwa imfucuza.
