Ulwazi Lwereferensi
| Isicelo | I-2, 6-dichloro-4-iodopyridine ingasetshenziswa njengama-organic synthesis intermediates kanye ne-pharmaceutical intermediates, ikakhulukazi esetshenziselwa ucwaningo lwelabhorethri nenqubo yokuthuthukiswa kanye nenqubo yokukhiqiza amakhemikhali. |
Isingeniso
I-2,6-dichloro-4-iodopyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-2,6-Dichloro-4-iodopyridine iyimpushana ecwebezelayo emhlophe kuya kokuphuzi.
- Izinzile ezingeni lokushisa lasekamelweni, kodwa iyakwazi kalula ukukhanya nomswakama.
Inokuncibilika okuthile kuzincibilikisi, njenge-methanol ne-methylene chloride.
- Amagesi anobuthi akhululwa ngesikhathi somlilo.
Sebenzisa:
I-2,6-Dichloro-4-iodopyridine iyingxenye ebalulekile ye-organic engasetshenziswa ekuhlanganiseni ezinye izinhlanganisela.
Indlela:
- 2,6-Dichloro-4-iodopyridine ngokuvamile itholakala ngokusabela kwe-pyridine iodide ne-cuprous chloride ku-solvent efanele.
- Ukusabela kudinga ukusetshenziswa kwezimo ezifanele zokusabela kanye nama-catalyst, ngokuvamile endaweni engasebenzi.
Ulwazi Lokuphepha:
- I-2,6-Dichloro-4-iodopyridine iyinhlanganisela yemvelo enobuthi futhi ecasulayo.
- Gqoka izinyathelo zokuphepha ezifanele, njengezingubo zamehlo ezivikelayo namagilavu, ngesikhathi sokuphatha nokusebenzisa.
- Gwema ukuhogela, ukuthinta isikhumba namehlo, futhi ugweme ukugwinya.
- Gwema ukuthintana nezinto ezifana nama-oxidants nama-asidi aqinile.
- Funda futhi ulandele imihlahlandlela yokusebenza kwezokuphepha efanele kanye nezinqubo zokusebenza ngokucophelela ngaphambi kokusetshenziswa. Lapho isetshenziswa endaweni yaselabhorethri, izinqubo ezifanele zokusebenza zokuphepha kufanele zibhekwe.
