I-2-Fluoro-3-nitropyridine (CAS# 1480-87-1)

I-2-Fluoro-3-nitropyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, inhloso, indlela yokukhiqiza, kanye nolwazi lokuphepha:

imvelo:
-Ukubukeka: I-2-Fluoro-3-nitropyridine iyimpushana ye-crystalline engenambala ephuzi ephuzi;
-Ingabola noma iqhume emazingeni okushisa aphezulu.

Inhloso:
-Ingasetshenziswa njengezinto zokwenziwa zokwenziwa kwezibulala-zinambuzane, odayi, iziqhumane, njll.
-Ingasetshenziswa futhi ekuphenduleni kwe-organic synthesis, njengokusabela kokushintshanisa nokusabela kwe-fluorination.

Indlela yokukhiqiza:
-Kunezindlela eziningi zokulungiselela i-2-fluoro-3-nitropyridine, futhi enye yezindlela ezijwayelekile yethulwa ngezansi:
1. Ukusabela ku-2,3-dibromopyridine nge-nitrite yesiliva ukuthola i-2-nitro-3-bromopyridine;
2. Sabela i-2-nitro-3-bromopyridine ne-hydrogen fluoride ngaphansi kwezimo ze-alkaline ukukhiqiza i-2-fluoro-3-nitropyridine.

Ulwazi lokuphepha:
-2-Fluoro-3-nitropyridine iyinhlanganisela yezinto eziphilayo ezinobuthi obuthile nokuvutha;
-Gwema ukuthintana nesikhumba, amehlo, nemigudu yokuphefumula;
-Uma udliwe noma uhogelwe ngephutha, funa usizo lwezempilo ngokushesha.
