Isingeniso
I-2-Bromo-5-chloropyridine iyinhlanganisela yezinto eziphilayo, okulandelayo yisingeniso kwezinye izakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-bromo-5-chloropyridine:
Ikhwalithi:
1. Ukubukeka: I-2-bromo-5-chloropyridine iqinile elingenambala ukuya kokuphuzi okuphaphathekile.
3. Ukunyibilika: I-2-bromo-5-chloropyridine inokuncibilika okuhle kuzincibilikisi ezivamile eziphilayo, njenge-ethanol, i-acetone ne-dimethyl thionite ether.
Sebenzisa:
1. Ama-Chemical reagents: I-2-bromo-5-chloropyridine ivame ukusetshenziswa njenge-reagent ku-organic synthesis.
2. Izibulala-zinambuzane: Iphinde isetshenziswe ekuhlanganiseni izibulala-zinambuzane njengezinto ezingavuthiwe zokubulala izinambuzane noma izibulala-khula.
Indlela:
Ukulungiswa kwe-2-bromo-5-chloropyridine kungatholakala ngokusabela kwe-2-chloropyridine nge-hydrobromic acid. Izinyathelo eziqondile zihlanganisa ukuqedwa kwe-2-chloropyridine ku-anhydrous cyclohexane, ukwengeza i-hydrobromic acid, ukushisa ukusabela nokugqugquzela, ngemva kokuqeda ukusabela, isigaba se-organic esiwumphumela sihlukaniswa ngamanzi kanye nesisombululo se-sodium chloride egcwele, futhi umkhiqizo ohlosiwe uhlanzwa ngokumiswa. ukwelashwa kanye ne-distillation.
Ulwazi Lokuphepha:
1. I-2-Bromo-5-chloropyridine inemiphumela engaba yi-carcinogenic kanye nobuthi ohlelweni lokuzala, futhi kufanele kuthathwe izinyathelo zokuqapha ngesikhathi sokusetshenziswa.
2. Gwema ukuthinta isikhumba namehlo.
3. Lapho usebenzisa futhi uyigcina, kufanele igcinwe kude nomlilo nemithombo yokushisa.
4. Izimo zokungenisa umoya ezinhle kufanele zigcinwe ngesikhathi sokusebenza.
5. Sicela ulandele ngokuqinile izinqubo zokuphepha ezifanele futhi usebenzise izinto zokuzivikela.
