2-Chloro-3-nitropyridine (CAS# 5470-18-8)

Isingeniso

I-2-Chloro-3-nitropyridine iyinhlanganisela ye-organic ene-chemical formula C5H3ClN2O2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

Imvelo:

-Ukubukeka: Ayinambala ikristale ephuzi

-indawo yokuncibilika: 82-84 ℃

-Indawo yokubilisa: 274-276 ℃

-Ukuminyana: 1.62g/cm3

-I-Solubility: Incibilika kancane emanzini, i-soluble ku-organic solvents njenge-ethanol, i-dimethylformamide, njll.

Sebenzisa:

- I-2-Chloro-3-nitropyridine ingasetshenziswa njengama-organic synthesis intermediates, asetshenziswa kabanzi kuma-pesticides, imithi kanye nodayi neminye imikhakha.

-Ezibulala-zinambuzane, imvamisa isetshenziswa njengezinto ezingavuthiwe ezibulala izinambuzane nezibulala fungi.

-Emkhakheni wezokwelapha, ingasetshenziswa ukuhlanganisa ama-antibiotics nezinye izidakamizwa.

-Ngaphezu kwalokho, i-2-Chloro-3-nitropyridine ingasetshenziswa futhi njengama-catalysts nama-catalytic reagents ekuphenduleni kwe-organic synthesis.

Indlela Yokulungiselela:

- I-2-Chloro-3-nitropyridine ingatholakala ngokuphendula i-pyridine nge-chlorine ne-nitric acid. Ukusabela ngokuvamile kwenziwa ngaphansi kokuvikelwa kwegesi ye-inert, futhi izinga lokushisa lokuphendula kanye nesikhathi sokusabela kuzothinta isivuno nokuhlanzeka komkhiqizo.

Ulwazi Lokuphepha:

- I-2-Chloro-3-nitropyridine inobungozi obuthile, sicela uhambisane nemininingwane yokusebenza kokuphepha efanele.

-Gwema ukuthinta isikhumba namehlo ngesikhathi sokusebenza, futhi unake izinyathelo zokuzivikela, njengokugqoka amagilavu, izibuko nezingubo zokuzivikela.

-Inhlanganisela kufanele igcinwe endaweni eyomile, epholile, engenamoya, futhi kude nomlilo nezinto ezivuthayo.

-Gcina imithetho kazwelonke neyesifunda kanye neziqondiso lapho uphatha into.
