2 3-DIBROMO-5-CHLORO PYRIDINE (CAS# 137628-17-2) nhanganyaya
2,3-dibromo-5-chloropyridine is an organic compound. Iyi inotevera sumo yezvivakwa, mashandisirwo, nzira dzekugadzirira, uye ruzivo rwekuchengetedza kwekomboni:
nature:
-Kuonekwa: 2,3-dibromo-5-chloropyridine haina ruvara kune yero yakasimba.
-Solubility: Iine yakanyanya solubility muorganic solvents asi yakaderera solubility mumvura.
Chinangwa:
2,3-dibromo-5-chloropyridine ine huwandu hwakawanda hwemashandisirwo mune organic synthesis, inonyanya kushandiswa munzvimbo dzinotevera:
-Sephotosensitizer, inogona kushandiswa muminda yakadai sekudhinda uye kugadzirwa kwemifananidzo.
Kugadzira nzira:
Nzira yekugadzirira ye2,3-dibromo-5-chloropyridine inogona kuitwa kuburikidza nematanho anotevera:
Pasi pemamiriro akakodzera, ita 2,3-dibromopyridine ne phosphorus pentachloride kuti ibudise 2,3-dibromo-5-chloropyridine pentachloride.
Zvadaro, react pentachloride ne sodium hydroxide kana mamwe alkaline mhinduro kuwana 2,3-dibromo-5-chloropyridine.
Chekuchengetedza ruzivo:
-Kushandiswa uye kushanda kwe2,3-dibromo-5-chloropyridine kunofanira kuitwa munzvimbo ine mhepo inofefetera kuti irege kutarisana kwenguva refu nekunhuhwirira kwayo kana guruva.
-Panguva yekushanda, midziyo yekudzivirira inofanirwa kupfekwa, kusanganisira magirovhosi ekudzivirira emakemikari, magirazi uye zvipfeko zvekudzivirira.
-2,3-dibromo-5-chloropyridine ndeye organic bromides uye ine humwe huturu uye kusagadzikana. Inofanirwa kubatwa uye kuchengetwa zvakanaka kuti isasangana nezvinopisa uye kupisa kwakanyanya.
-Paunenge uchishandisa uye kurasa komisheni iyi, ndapota tevera zvinodiwa zvekuchengetedza maitiro uye nemitemo yakakodzera.
