3-Bromo-2-chloro-5-(trifluoromethyl)pyridine(CAS# 71701-92-3)
Ubungozi Nokuphepha
| Amakhodi Engozi | R25 – Kunobuthi uma ugwinywe R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | S7/9 - S22 - Ungaphefumuli uthuli. I-S24/25 - Gwema ukuthintana nesikhumba namehlo. S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu. I-S38 – Uma kungekho kungena komoya okwanele, gqoka izinto zokuphefumula ezifanele. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) S51 – Sebenzisa kuphela ezindaweni ezinomoya ohlanzekile. |

Isingeniso
I-compound inezinhlelo zokusebenza ezibalulekile ekuhlanganiseni kwezidakamizwa kanye nokuhlanganiswa kwezibulala-zinambuzane. Ingasetshenziswa njengendawo emaphakathi yokuhlanganiswa kwezinto eziphilayo ezisebenzayo. Isibonelo, ingasetshenziselwa ukuhlanganiswa kwezidakamizwa ezilwa namagciwane kanye nezibulala-zinambuzane, njll.
I-3-Bromo-2-chloro-5-(trifluoromethyl)pyridine ingalungiswa ngezindlela ezahlukene. Indlela evamile ukwethula ama-athomu e-bromine ne-chlorine ekuphenduleni nge-bromination kanye ne-chlorination, ngokulandelana, kuqala nge-pyridine. Bese, iqembu le-trifluoromethyl lethulwa ngokusabela kwe-trifluoromethylation. Lokhu kuhlanganisa ngokuvamile kwenziwa ngaphansi komkhathi ongasebenzi ukuze kuqinisekiswe ukukhetha okuphezulu kanye nesivuno sokusabela.
I-3-Bromo-2-chloro-5-(trifluoromethyl)pyridine inolwazi olulinganiselwe lokuphepha. Kungase kucasule amehlo, uhlelo lokuphefumula kanye nesikhumba. Ngesikhathi sokusetshenziswa, ukunakekelwa kufanele kuthathwe ukugwema ukuthintana ngqo nesikhumba namehlo. Ngesikhathi esifanayo, izinyathelo zokuzivikela ezifanele kufanele zithathwe ngesikhathi sokusebenza, njengokugqoka izibuko zokuzivikela, amagilavu nezingubo zokuzivikela.
Ngaphezu kwalokho, ngesikhathi sokuphatha nokugcinwa, ukunakekelwa kufanele kuthathwe ukuvimbela ukuthintana nezinto ezivuthayo futhi kugcinwe umoya omuhle. Lapho kulahlwa imfucuza, kufanele kulandelwe imithetho yendawo futhi kwamukelwe izindlela ezifanele zokulahla imfucuza. Isetshenziswa kangcono futhi isingathwe ngaphansi kokuqondisa kosokhemisi abanolwazi.
