2-FLUORO-3-NITRO-4-PICOLINE (CAS# 19346-43-1) Intshayelelo

I-organic compound kunye ne-chemical formula C6H5FN2O2. Oku kulandelayo sintshayelelo ngobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:Indalo:
sisisindi esingenambala ukuya kumthubi. Izinzile kwiqondo lokushisa eliqhelekileyo kwaye ayinyibiliki emanzini, kodwa i-soluble kwi-solvents eziphilayo ezifana ne-ethanol kunye ne-dimethylformamide. Yikhompawundi yealkaline ebuthathaka.

Sebenzisa:
Isetyenziswa ikakhulu njengento ebalulekileyo ephakathi kwi-organic synthesis. Ingasetyenziselwa ukulungiselela iintlobo ezahlukeneyo zeekhompawundi ezifana neziyobisi, iidayi kunye nezibulala-zinambuzane. Ihlala isetyenziswa njengento ekrwada ye-antibiotics, i-anticancer drugs kunye ne-pesticides kwi-pharmaceutical field.

Indlela:
Ukulungiswa kwe-mercury kunokufezekiswa ngeendlela ezahlukeneyo. Indlela eqhelekileyo kukusabela i-4-picoline kunye ne-hydrogen fluoride okanye i-sodium fluoride kwaye emva koko nge-nitric acid ukufumana imveliso efunekayo.

Ulwazi ngoKhuseleko:
Yeyokuxutywa kwezinto eziphilayo kwaye inetyhefu ethile. Kwinkqubo yokusebenza kunye nokusetyenziswa, kuyimfuneko ukuthatha amanyathelo afanelekileyo okukhusela, kuquka ukugqoka iiglavu, izibuko, iimpahla zokukhusela, njl. Ngexesha lokugcinwa kunye nokuphatha, kufuneka kuthathelwe ingqalelo ukuphepha umlilo kwaye ugweme ukudibanisa ne-oxidants, i-acids eqinile kunye nezinye izinto. Xa ulahla inkunkuma, kufuneka ilahlwe ngokuhambelana nemimiselo ehambelanayo yokuthintela ukungcoliseka kwendalo.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
