Isingeniso

I-Ethyl 2-bromopyridine-4-carboxylate iyinhlanganisela yemvelo enezici ezilandelayo:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala kuya kokuphuzi okuphaphathekile

- Ukunyibilika: Kuncibilika kancane emanzini, kuncibilika kuzincibilikisi zemvelo ezifana ne-ethanol ne-ether

 

Sebenzisa:

 

Indlela:

I-Ethyl 2-bromopyridine-4-carboxylate ingalungiswa ngokusabela kwe-2-bromopyridine nge-acetic anhydride.

 

Ulwazi Lokuphepha:

- I-Ethyl 2-bromopyridine-4-carboxylate ingase icasule futhi idle esikhumbeni, emehlweni, nolwelwesi lwamafinyila, futhi idinga izinto zokuzivikela lapho iphathwa.

- Ukuhogela umhwamuko kufanele kugwenywe futhi kugcinwe indawo enomoya omuhle.

- Gcina kude nomlilo kanye namalangabi avulekile futhi ugcine endaweni eyomile, epholile.

- Kufanele kuqashelwe ukulandela izinqubo zokusebenza zamakhemikhali eziphephile ngesikhathi sokusetshenziswa nokuphathwa.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
