2′-Chloro-4-fluoroacetophenone (CAS# 456-04-2)
| Iikhowudi zoMngcipheko | R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. I-R34 – Ibangela ukutsha I-R23/25 – Ityhefu ngokuphefumlelwa kwaye ukuba iginyiwe. R36 – Iyandicaphukisa emehlweni |
| Inkcazelo yoKhuseleko | S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S28 – Emva kokudibana nolusu, hlamba ngoko nangoko ngeesepha ezininzi. S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) S36/37/39 – Nxiba iimpahla ezifanelekileyo zokukhusela, iiglavu kunye nokukhusela amehlo/ubuso. S27 – Khulula ngoko nangoko zonke iimpahla ezosulelekileyo. |

Intshayelelo
I-2-Chloro-4′-fluoroacetophenone i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: 2-Chloro-4′-fluoroacetophenone lulwelo olungenambala ukuya kumthubi.
- Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo ezifana nekloroform, i-ethanol kunye ne-ether.
Sebenzisa:
- Uphando lweMichiza: I-2-chloro-4′-i-fluoroacetophenone yinto eqhelekileyo esetyenziswa phakathi kwi-organic synthesis kwaye ingasetyenziselwa ukuhlanganiswa kwamanye ama-organic compounds.
Indlela:
- Kukho iindlela ezininzi zokulungiselela i-2-chloro-4′-fluoroacetophenone, kwaye enye yeendlela ezisetyenziswa ngokuqhelekileyo ifunyenwe nge-fluorination ye-chloroacetophenone. Amanyathelo athile abandakanya ukongeza i-hydrofluoric acid kunye ne-sodium palladium hydroxide catalyst kwi-solvent yokusabela ukusabela kwi-chloroacetophenone ngegesi ye-fluorine ukuvelisa i-2-chloro-4′-fluoroacetophenone.
Ulwazi ngoKhuseleko:
- I-2-Chloro-4′-fluoroacetophenone i-organic compound, kunye neempawu zayo ezinokuthi zibe yingozi zifuna ukuphathwa ngokucophelela.
- Xa usebenzisa okanye ugcina, kunqande ukudibana nezinto ezinokutsha, ii-oxidizing agents ezinamandla, kunye neeasidi ezinamandla.
- Ukungena komoya okwaneleyo kufuneka kuthatyathwe ngexesha lomsebenzi kwaye izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu kunye nezibuko zokhuseleko kufuneka zinxitywe.
