Intshayelelo
Iipropati: Inonyibiliko oluphantsi emanzini kunye nokunyibilika okulungileyo kwizinyibilikisi eziphilayo. Iimpawu zayo zeekhemikhali ziyasebenza kwaye zixhomekeke ekunciphiseni, i-alkylation kunye nezinye iimpendulo.
Sebenzisa:
I-2-hydroxy-3-nitro-5-chloropyridine inexabiso elithile lesicelo kwi-organic synthesis. Ingasetyenziswa njengento ebalulekileyo ephakathi kwi-organic synthesis kwaye ibandakanyeka kwiimpendulo ezininzi ze-organic synthesis, ezifana ne-synthesis ye-hop flavour compounds.
Indlela:
Kukho iindlela ezininzi zokulungiselela i-2-hydroxy-3-nitro-5-chloropyridine, indlela eqhelekileyo ifunyenwe nge-nitrification ye-2-azacyclopentadiene, kwaye emva koko i-hydrogenation kunye nokuphendula kwe-chlorination ukufumana imveliso ekujoliswe kuyo.
Ulwazi ngoKhuseleko:
Kuphephe ukudibana nee-oxidants ezinamandla, iiasidi ezinamandla, iialkali ezinamandla kunye nezinye izinto ukuphepha ukuphendula ngobundlobongela.
Nika ingqalelo kumanyathelo okukhusela ngexesha lokusetyenziswa, kwaye unxibe izixhobo ezifanelekileyo zokuzikhusela, ezinjengeeglavu zokhuseleko, iiglavu, njl.
Xa usebenzisa okanye ugcina, gcina i-2-hydroxy-3-nitro-5-chloropyridine kwindawo epholileyo, engenamoya, kude nomlilo namaqondo obushushu aphezulu.
