5-CHLORO-2-FLUORO-3-NITROPYRIDINE(CAS# 60186-16-5)
| Izimpawu Eziyingozi | I-Xn - Iyingozi |
| Amakhodi Engozi | R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. I-R22 – Iyingozi uma igwinywe |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36 – Gqoka izingubo ezifanele zokuzivikela. |
| Inothi Lengozi | Kuyingozi |
Isingeniso
Kuyinhlanganisela ye-organic ifomula yayo yamakhemikhali ithi C5H2ClFN2O2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: Impushana eqinile emhlophe iye kokukhanya okuphuzi.
-Iphuzu elincibilikayo: Iphuzu lokuncibilika kwenhlanganisela lingaba ngu-160-165 degrees Celsius.
-I-Solubility: Ingancibilika kuma-solvents ephilayo njenge-dimethylmethylphosphinate ne-dimethylformamide, kodwa ukuncibilika kwayo emanzini kuphansi.
Sebenzisa:
-Enye yezinto ezisetshenziswa kakhulu isibulala-zinambuzane isibulala-zinambuzane nesibulala-sikhunta emkhakheni wezolimo.
-Ingase futhi isetshenziselwe ukuhlanganisa ezinye izinhlanganisela eziphilayo, ezifana zokwenziwa intermediates izidakamizwa kanye nezibulala-zinambuzane.
Indlela Yokulungiselela:
-noma ingahlanganiswa ngokusabela kwe-nitro. Indlela yokwenziwa evame kakhulu ukusabela kwe-5-chloro-2-aminopyridine nge-nitrite, kulandelwa i-fluorination nge-reagent fluorinating.
Ulwazi Lokuphepha:
-iyinhlanganisela yezinto eziphilayo futhi kufanele isetshenziswe ngokuhambisana nezinqubo zokuphepha ezifanele.
-Kungase kube yingozi emvelweni, futhi kufanele kuthathwe izinyathelo zokuvikela ukunciphisa umthelela wayo emvelweni.
-Gqoka amagilavu okuzivikela, izibuko zokuphepha nezingubo zokuzivikela lapho usebenzisa noma uphethe lesi sithako.
-Kufanele agcinwe endaweni eyomile, epholile, futhi kude nezinto ezivuthayo nezibulalayo.
-Ngaphambi kokusetshenziswa, kufanele uqonde idatha yokuphepha mayelana nenhlanganisela ngokuningiliziwe futhi ulandele izindlela zayo zokuphatha nezindlela zokulahla.
