Isingeniso
I-2-Chloro-3-amino-5-bromopyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo isingeniso esifushane sobunjalo bayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: Amakristalu amhlophe kuya kokuphuzi
- Ukunyibilika: Incibilika ku-chloroform ne-ethanol, inyibilika kancane emanzini
Sebenzisa:
- I-compound ingasetshenziswa futhi njenge-catalyst ku-organic synthesis futhi idlala indima ebalulekile ekuhlanganiseni kwamanye ama-organic compounds.
Indlela:
- Ukuhlanganiswa kwe-2-chloro-3-amino-5-bromopyridine kuvame ukwenziwa kusetshenziswa ukusabela kwe-chlorination-bromination. Ilungiswa ngokusabela kwe-3-amino-4-bromopyridine nge-chlorinating agents (njenge-phosphorus trichloride, i-sulfuryl chloride, njll.).
Ulwazi Lokuphepha:
- I-2-Chloro-3-amino-5-bromopyridine iyikhemikhali futhi idinga izinyathelo zokuphepha ezifanele njengokugqoka amagilavu amakhemikhali namamaski.
- Uma usebenzisa futhi ulondoloza, ukuthintana nama-oxidants, ama-asidi aqinile, nama-alkali aqinile kufanele kugwenywe ukuze kugwenywe ukusabela okuyingozi.
- Kungaba ikhemikhali enokhahlo esikhumbeni, emehlweni, nasezimisweni zokuphefumula, futhi kufanele ihashazwe ngamanzi ngokushesha ngemva kokuyithinta futhi kufunwe nokwelashwa.
