Ubungozi Nokuphepha
| Amakhodi Engozi | R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. I-R22 – Iyingozi uma igwinywe |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) S36 – Gqoka izingubo ezifanele zokuzivikela. I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu. S23 – Ungawuphefumuli umhwamuko. I-S9 – Gcina isiqukathi endaweni enomoya omuhle. |

2-Cyano-5-fluorobenzotrifluoride (CAS# 194853-86-6) Isingeniso
I-4-fluoro-2-(trifluoromethyl)benzonitrile iyikristalu engenambala noma eqinile enephunga elimnandi elinamandla. Inokuqina okuhle kanye nokuzinza kokushisa ekamelweni lokushisa, futhi ayincibiliki emanzini, kodwa iyancibilika kuma-solvents amaningi e-organic.
Sebenzisa:
I-4-fluoro-2-(trifluoromethyl)benzonitril iyingxenye ebalulekile ye-organic engadlala indima ebalulekile ekuhlanganisweni kwezidakamizwa, izibulala-zinambuzane namakhemikhali akhethekile. Ingasetshenziswa ekuhlanganiseni izidakamizwa, ama-fungicides, ama-antioxidant nezinye izinhlanganisela, kodwa futhi ingasetshenziswa njengodayi kanye nokuthambisa izinto zokusetshenziswa.
Indlela:
Indlela evamile yokulungiselela i-4-fluoro-2-(trifluoromethyl)benzonitrile ifinyelelwa ngokusabela kwe-fluorination kanye nokusabela kwe-cynation. Indlela eyodwa evamile iwukusabela i-2,4-difluoro-1-chlorobenzene ne-trifluoronitrile ukunikeza umkhiqizo.
Ulwazi Lokuphepha:
Gqoka amagilavu okuvikela amakhemikhali, izibuko nezingubo zokuzivikela lapho uphethe i-4-fluoro-2-(trifluoromethyl)benzonitril. Gwema ukuthinta isikhumba kanye nokuhogela umhwamuko. Uma uthintana ngengozi, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha. Uma igcinwe, kufanele ibekwe endaweni eyomile, epholile, engenawo umoya, kude nomlilo kanye ne-oxidant. Landela izinqubo zokuphepha ezifanele kanye neziqondiso.
