Isingeniso
I-5-Chloro-2-cyanopyridine iyinhlanganisela ye-organic ene-chemical formula C6H3ClN2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: I-5-Chloro-2-cyanopyridine iyi-crystalline eqinile engenambala ukuya kokuphuzi okuphaphathekile.
-Indawo yokuncibilika: Iphuzu layo lokuncibilika lingama-85-87°C.
-I-Solubility: I-solubility enhle kuzincibilikisi ezivamile ze-organic.
Sebenzisa:
- I-5-Chloro-2-cyanopyridine ivame ukusetshenziswa njengenhlanganisela ephakathi ku-organic synthesis.
-Kuyinto ebalulekile yokwakheka kwezinhlanganisela ezifana nezidakamizwa, izibulala-zinambuzane namadayi.
-Ingasetshenziswa futhi njenge-substrate ye-organic synthesis catalysts.
Indlela Yokulungiselela:
- I-5-Chloro-2-cyanopyridine ingatholakala ngokugcoba i-2-cyanopyridine.
-Ukusabela kuvame ukwenziwa ngaphansi kwezimo ze-alkali ukuze kuthuthukiswe ukusebenza kahle kokusabela.
-Ngokuvamile, i-reagent efana ne-stannous chloride noma i-antimony chloride isetshenziswa njenge-agent e-chlorinating ekuphenduleni.
Ulwazi Lokuphepha:
- I-5-Chloro-2-cyanopyridine iyacasula futhi kufanele ihashazwe ngamanzi ngokushesha lapho ithinta isikhumba noma amehlo.
-Lapho usebenza, gqoka amagilavu okuzivikela afanelekile kanye nezibuko ukuze uqinisekise ukuphepha.
-Inhlanganisela kufanele igcinwe kude nomlilo kanye nezinga lokushisa eliphezulu ukuvimbela umlilo nokuqhuma.
-Kufanele agcinwe esitsheni esivaliwe futhi kude nama-oxidants nama-acids aqinile.
Sicela uqaphele ukuthi lesi yisingeniso esijwayelekile kuphela, ukusetshenziswa okuqondile kufanele futhi kubhekisele ezincwadini zamakhemikhali ezifanele kanye namaphepha edatha yokuphepha.
