2′-Chloro-4-fluoroacetophenone (CAS# 456-04-2)
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R34 – Ibangela ukusha R23/25 – Kunobuthi ngokuhogela umoya futhi uma ugwinywe. R36 – Ukucasuka emehlweni |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. I-S28 – Ngemva kokuxhumana nesikhumba, geza ngokushesha ngensipho eningi. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S27 – Khumula ngokushesha zonke izingubo ezingcolile. |

Isingeniso
I-2-Chloro-4′-fluoroacetophenone iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-2-Chloro-4′-fluoroacetophenone iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile.
- Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo njenge-chloroform, i-ethanol ne-ether.
Sebenzisa:
- Ucwaningo lwamakhemikhali: I-2-chloro-4′-fluoroacetophenone iyindawo evame ukusetshenziswa phakathi ku-organic synthesis futhi ingasetshenziswa ekuhlanganiseni ezinye izinhlanganisela eziphilayo.
Indlela:
- Ziningi izindlela zokulungiselela i-2-chloro-4′-fluoroacetophenone, futhi enye yezindlela ezisetshenziswa kakhulu itholakala ngokufakwa kwe-fluorination ye-chloroacetophenone. Izinyathelo eziqondile zihlanganisa ukungeza i-hydrofluoric acid kanye ne-sodium palladium hydroxide catalyst ku-solvent yokusabela ukuze kusabele i-chloroacetophenone nge-fluorine gas ukukhiqiza i-2-chloro-4′-fluoroacetophenone.
Ulwazi Lokuphepha:
- I-2-Chloro-4′-fluoroacetophenone iyinhlanganisela yezinto eziphilayo, futhi izici zayo ezingase zibe yingozi zidinga ukuphathwa ngokucophelela.
- Uma usebenzisa noma ulondoloza, gwema ukuthintana nezinto ezivuthayo, ama-oxidizing aqinile, nama-asidi aqinile.
- Ukungena komoya owanele kufanele kuthathwe ngesikhathi sokusebenza futhi izinto zokuzivikela ezifanele ezifana namagilavu nezibuko zokuphepha kufanele zigqokwe.
