2-Cyano-3-nitropyridine (CAS# 51315-07-2)

Intshayelelo

3-nitro-2-cyanopyridine.

Umgangatho:

I-3-nitro-2-cyanopyridine yikristale engenambala eqinileyo, enganyibiliki emanzini kwiqondo lokushisa, i-soluble kwi-solvents eziphilayo ezifana ne-ethanol, i-ether kunye ne-acetone. Inevumba elibukhali elibukhali.

Sebenzisa:

I-3-Nitro-2-cyanopyridine isetyenziswa ngokuqhelekileyo njenge-reagent yekhemikhali ye-cyanoation kunye ne-electrophilic nitrification kwi-organic synthesis reactions. Isenokusetyenziswa njengendawo ephakathi kwidayi kunye neepigments zokwenziwa kwedayi eziphilayo.

Indlela:

I-3-Nitro-2-cyanopyridine inokulungiswa nge-nitrosylation kunye ne-cyanoation reactions ye-benzene. I-Benzene inokusabela nge-asidi ye-nitric ukufumana i-phenyl nitro compounds, ethi ke iguqulelwe kwi-3-nitro-2-cyanopyridine nge-cyanoation phantsi kweemeko ze-alkaline.

Ulwazi ngoKhuseleko:

I-3-Nitro-2-cyanopyridine iyacaphukisa kwaye iyatsha. Iiglavu zokhuselo lwekhemikhali, iiglavu, izikhuselo zobuso kufuneka zinxitywe ukuqinisekisa indawo yelabhoratri engena umoya kakuhle.
