2-Fluorobenzonitrile (CAS# 394-47-8)
Umngcipheko kunye noKhuseleko
| Iikhowudi zoMngcipheko | I-R22 – Iyingozi xa iginyiwe I-R37/38 – Iyacaphukisa inkqubo yokuphefumla kunye nolusu. I-R41 – Umngcipheko womonakalo omkhulu emehlweni R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. I-R20/21/22 – Iyingozi ngokuphefumla, xa udibana nolusu naxa uginyiwe. |
| Inkcazelo yoKhuseleko | S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S39 –Nxiba ukhuseleko lwamehlo / ubuso. S36/37/39 – Nxiba iimpahla ezikhuselayo ezifanelekileyo, iiglavu kunye nokhuseleko lwamehlo/ubuso. S36 – Nxiba iimpahla ezifanelekileyo ezikhuselayo. |
2-Fluorobenzonitrile(CAS#394-47-8) Intshayelelo
2-FluorobenzonitrileYikhompawundi ephilayo. Lulwelo olungenambala ukuya kumthubi oluluthuthu olunevumba elinamandla. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2-fluorobenzonitrile:
Iinkcazelo ngeempawu:
- I-2-Fluorobenzonitrile i-liquid engabonakaliyo emanzini kwaye inoxinzelelo oluphantsi lomphunga kwiqondo lokushisa.
- Ine-solubility efanelekileyo kwaye inokunyibilika kwizinto ezininzi ze-organic solvents ezifana ne-ethanol, i-acetone kunye ne-dimethylformamide.
- Izinzile emoyeni, kodwa ukusabela kweekhemikhali ezinobungozi kunokwenzeka xa kushushu kumaqondo aphezulu okanye ukudibana nee-oxidants ezinamandla.
Usebenzisa:
- Isenokusetyenziswa njengento ekrwada yokwaleka, iidayi kunye neziqholo.
Indlela yokulungiselela:
- Kukho iindlela ezimbini eziphambili zokulungiselela i-2-fluorobenzonitrile: indlela yokutshintsha i-cyanide kunye nendlela yokutshintsha i-fluoride.
- Indlela yokutshintsha icyanide ibhekisa ekufakweni kweqela lecyano endaweni yeringi yebenzene kwaye emva koko kungeniswe iiathom zefluorine endaweni yeqela lecyano.
-Indlela yokutshintsha iFluoride ibhekisa kusetyenziso lwefluoride njengento ekrwada, isabela ngeklorini, ibromine okanye ihaloform kwiringi yebenzene, endaweni yeklorine, ibromine okanye ihaloform ngefluorine ukufumana i-2-fluorobenzonitrile.
Ulwazi ngoKhuseleko:
- I-2-Fluorobenzonitrile inetyhefu kumzimba womntu. Nceda uthintele ukudibana ngqo nolusu, amehlo kunye nokuphefumla umphunga walo.
- Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglasi zokhuseleko kunye nempahla yokukhusela ngexesha lokusebenza.
- Xa ugcina, i-2-fluorobenzonitrile kufuneka ifakwe kwisitya esivaliweyo, kude nomlilo kunye ne-oxidants, kwaye igcinwe ngokufanelekileyo ukuphepha ukuvuza kunye neempembelelo.
