2-Bromo-3-methyl-5-chloropyridine (CAS# 65550-77-8)
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R41 – Ingozi yokulimala okubi emehlweni R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba. I-R22 – Iyingozi uma igwinywe |
| Incazelo Yokuphepha | I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S39 – Gqoka ukuvikela iso / ubuso. |
Isingeniso
I-2-Bromo-5-chloro-3-picoline iyinhlanganisela ye-organic enefomula yamakhemikhali ethi C7H6BrClN. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:
Imvelo:
-Ukubukeka: 2-Bromo-5-chloro-3-picolini uketshezi olungenambala noma oluphuzi kancane.
-I-Solubility: Incibilika kuzincibilikisi eziningi eziphilayo, njenge-ethanol, i-dimethylformamide ne-chloroform.
-Iphuzu lokuncibilika nendawo yokubilisa: Iphuzu lokuncibilika kwenhlanganisela lingaba -35°C, kanti indawo yokubilisa icishe ibe ngu-205-210°C.
Sebenzisa:
- I-2-Bromo-5-chloro-3-picoline ingasetshenziswa njengento yokuqala noma emaphakathi ku-organic synthesis, futhi ingasetshenziswa ukuhlanganisa ezinye izinhlanganisela, njengezibulala-zinambuzane nezidakamizwa.
-Ibuye isetshenziswe kabanzi kuma-synthetic intermediates, ama-polychlorinated biphenyls, ama-polybrominated biphenyl kanye nezingulube.
Indlela Yokulungiselela:
- I-2-Bromo-5-chloro-3-picoline ivame ukulungiswa nge-bromination kanye ne-chlorination ye-3-picoline. Okokuqala, i-3-methylpyridine isabela nge-hydrogen bromide ukuze ithole i-2-bromo-5-methylpyridine, bese umkhiqizo usabela nge-catalyst yensimbi ye-chloride ukuze uthole umkhiqizo ohlosiwe.
Ulwazi Lokuphepha:
- I-2-Bromo-5-chloro-3-piccoline ngokuvamile ayibangeli umonakalo omkhulu ngaphansi kwezimo zokusetshenziswa ezivamile. Kodwa-ke, kungase kucasule amehlo, isikhumba kanye nomgudu wokuphefumula, ngakho-ke kufanele kuqashelwe ukugwema ukuthintana ngqo.
-Sebenzisa ngezinto zokuzivikela ezifanele, njengamagilavu amakhemikhali, izibuko nezihlangu zobuso.
-Imikhuba emihle yaselabhorethri kufanele ilandelwe ngesikhathi sokusetshenziswa futhi kugcinwe umoya omuhle.
-Gwema ukuthintana nama-oxidants aqinile nama-acids aqinile ngesikhathi sokuphatha nokugcina.
