2-Fluorobenzonitrile (CAS# 394-47-8)
Ubungozi Nokuphepha
| Amakhodi Engozi | I-R22 – Iyingozi uma igwinywe R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba. R41 – Ingozi yokulimala okubi emehlweni R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S39 – Gqoka ukuvikela iso / ubuso. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S36 – Gqoka izingubo ezifanele zokuzivikela. |
2-Fluorobenzonitrile(CAS#394-47-8) Isingeniso
2-Fluorobenzonitrileiyinhlanganisela yezinto eziphilayo. Iwuketshezi oluphuzi ukuya kokuphaphathekile olunephunga elinamandla. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-fluorobenzonitrile:
Izakhiwo:
- I-2-Fluorobenzonitrile iwuketshezi olungenakunyakaziswa emanzini futhi lunomfutho ophansi womhwamuko ekamelweni lokushisa.
- Inoncibilika kahle futhi ingancibilika ezincibilikilweni eziningi eziphilayo njenge-ethanol, i-acetone ne-dimethylformamide.
- Azinzile emoyeni, kodwa ukusabela kwamakhemikhali okuyingozi kungase kwenzeke lapho kushisa kumazinga okushisa aphezulu noma kuthintana nama-oxidants aqinile.
Isebenzisa:
- Ingasetshenziswa futhi njengezinto ezingavuthiwe zokumboza, odayi namakha.
Indlela yokulungiselela:
- Kunezindlela ezimbili eziyinhloko zokulungiselela i-2-fluorobenzonitrile: indlela yokubuyisela i-cyanide kanye nendlela yokufaka i-fluoride.
- Indlela yokushintsha i-cyanide ibhekisela ekushintsheni kweqembu le-cyano iringi ye-benzene kanye nokwethulwa kwama-athomu e-fluorine ukuze athathe indawo yeqembu le-cyano.
- Indlela yokushintsha i-fluoride ibhekisela ekusetshenzisweni kwe-fluoride njengento eluhlaza, esabela nge-chlorine, i-bromine noma i-haloform eringini ye-benzene, esikhundleni se-chlorine, i-bromine noma i-haloform nge-fluorine ukuze kutholwe i-2-fluorobenzonitrile.
Ulwazi Lokuphepha:
I-2-Fluorobenzonitrile inobuthi emzimbeni womuntu. Sicela ugweme ukuthintana ngqo nesikhumba, amehlo kanye nokuhogela umhwamuko waso.
- Gqoka izinto zokuzivikela ezifanele ezifana namagilavu, izibuko zokuphepha nezingubo zokuzivikela ngesikhathi sokusebenza.
- Lapho ugcina, i-2-fluorobenzonitrile kufanele ifakwe esitsheni esivaliwe, kude nomlilo nama-oxidants, futhi igcinwe kahle ukuze kugwenywe ukuvuza kanye nomthelela.
