5-Chloro-2-fluoro-3-methylpyridine (CAS# 375368-84-6)
| Izimpawu Eziyingozi | I-Xn - Iyingozi |
| Amakhodi Engozi | I-R22 – Iyingozi uma igwinywe R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba. R41 – Ingozi yokulimala okubi emehlweni |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S39 – Gqoka ukuvikela iso / ubuso. |
Isingeniso
Kuyinhlanganisela yemvelo enefomula ethi C6H5ClFN. Iwuketshezi olungenambala olunephunga elikhethekile. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: uketshezi olungenambala
-Iphunga: Iphunga elikhethekile
-Ukuminyana: 1.36 g/mL
Iphuzu elibilayo: 137-139 ℃
-Indawo yokuncibilika:-4 ℃
-Ukunyibilika: Kuxubene nezinyibilikisi zemvelo, cishe ezingancibiliki emanzini.
Sebenzisa:
Isetshenziswa kabanzi ku-organic synthesis futhi ingasetshenziswa njenge-catalyst noma impahla eluhlaza. Inezinhlelo zokusebenza ezibalulekile ekuhlanganiseni izibulala-zinambuzane, imithi namakhemikhali, futhi ivame ukusetshenziswa ekwenzeni izibulala-zinambuzane, odayi, izinyibilikisi, njll.
Indlela Yokulungiselela: Indlela yokulungiselela ye
kuyinkimbinkimbi. Indlela evamile yokulungiselela ukuthola i-5-chloro -2-oxo -3-methyl pyridine nge-chloro-propionaldehyde reaction ngokusebenzisa i-pyridine njengento eluhlaza, futhi uthole umkhiqizo wokugcina ngokusabela kwe-fluorination.
Ulwazi Lokuphepha:
Kuyinhlanganisela ye-organic, futhi izinyathelo zokuphepha ezilandelayo kufanele zinakwe lapho uyisebenzisa:
-Ubuthi bungase bubangelwe ukuhogela, ukuthintana noma ukumunywa. Ukuxhumana okuqondile nesikhumba, amehlo kanye nolwelwesi lwamafinyila kufanele kugwenywe.
-Gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko nezingubo zokuzivikela uma zisetshenziswa.
-Gwema ukuthintana nama-oxidants, ama-asidi aqinile, izisekelo eziqinile nezinye izinto ukuze ugweme ukusabela okungaphephile.
-Uma ukuvuza kwenzeka, izinyathelo ezifanele kufanele zithathwe ukuze kuhlanzwe ukuvuza nokugwema ukungena ohlelweni lokudonsa amanzi kanye nemvelo.
Uma usebenzisa inhlanganisela, thatha izinyathelo zokuphepha ezihambisanayo ngokwesimo sangempela futhi ubhekisele ephepheni ledatha yokuphepha lenhlanganisela.
