2-Fluoro-5-nitropyridine (CAS# 456-24-6)

Isingeniso

I-2-Fluoro-5-nitropyridine (2-Fluoro-5-nitropyridine) iyinhlanganisela ye-organic ene-chemical formula C5H3FN2O2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

Imvelo:

-Ukubukeka: I-2-Fluoro-5-nitropyridine iqinile okumhlophe kuya kokuphuzi okuphaphathekile.

-I-Solubility: Ingancibilika kuma-solvents amaningi e-organic, njenge-ethanol, i-dimethylformamide ne-dichloromethane.

-Indawo yokuncibilika: Iphuzu layo lokuncibilika lilinganiselwa ku-78-81 degrees Celsius.

Sebenzisa:

I-2-Fluoro-5-nitropyridine iyinhlanganisela esebenzayo ye-organic synthesis, enokusetshenziswa okubalulekile ekwenzeni izidakamizwa nezibulala-zinambuzane.

-Ingasetshenziselwa ukuhlanganiswa kwenhlanganisela yezinto eziphilayo ezisebenzayo, njengemithi, odayi kanye nezingubo.

Indlela Yokulungiselela:

I-2-Fluoro-5-nitropyridine ngokuvamile ilungiswa nge-fluorination kanye ne-nitrate ye-pyridine.

-Indlela ethile yokulungiselela ingase iphendule i-pyridine ne-hydrogen fluoride noma i-ammonium fluoride ukuze ithole i-2-fluoropyridine. I-2-fluoropyridine bese isabela nge-nitric acid ukunikeza i-2-Fluoro-5-nitropyridine.

Ulwazi Lokuphepha:

- I-2-Fluoro-5-nitropyridine iyinhlanganisela yemvelo enezinga elithile lengozi. Enqubweni yokusebenza, kuyadingeka ukuthobela imithetho efanele yokusebenza kokuphepha.

-Kungase kucasule isikhumba namehlo, ngakho-ke izinyathelo zokuzivikela kufanele zithathwe lapho zibonakala, njengokugqoka amagilavu ​​okuzivikela kanye nezibuko.

-Uma udliwe ngephutha noma uhogelwe, funa usizo lwezempilo futhi unikeze izinyathelo zosizo lokuqala ezifanele.

-Ngesikhathi sokugcina, i-2-Fluoro-5-nitropyridine kufanele igcinwe endaweni eyomile, epholile, kude nomlilo kanye nama-oxidizing agents.
