Nhanganyaya
2-Bromo-5-chloro-3-picoline is an organic compound ine kemikari formula C7H6BrClN. Iyi inotevera tsananguro yezvivakwa, mashandisiro, kugadzirira uye kuchengetedza ruzivo rwekomboni:
Zvakasikwa:
-Kuonekwa: 2-Bromo-5-chloro-3-picoline imvura isina ruvara kana zvishoma yero.
-Solubility: Soluble mune zvakawanda organic solvents, akadai ethanol, dimethylformamide uye chloroform.
-Kunyunguduka uye nzvimbo yekubikira: Kunyunguduka kwekomboni inenge -35 ° C, uye nzvimbo yekuvira inenge 205-210 ° C.
Shandisa:
- 2-Bromo-5-chloro-3-picoline inogona kushandiswa sechinhu chekutanga kana chepakati mune organic synthesis, uye inogona kushandiswa kugadzira mamwe makomisheni, akadai semishonga yezvipembenene nemishonga.
-Iyo zvakare inoshandiswa zvakanyanya mu synthetic intermediates, polychlorinated biphenyls, polybrominated biphenyls uye pigments.
Kugadzirira nzira:
- 2-Bromo-5-chloro-3-picoline inowanzogadzirirwa nebromination uye chlorination ye 3-picoline. Kutanga, 3-methylpyridine inobatwa ne hydrogen bromide kuti iwane 2-bromo-5-methylpyridine, uye ipapo chigadzirwa chacho chinogadziriswa nesimbi chloride catalyst kuti iwane chigadzirwa chakanangwa.
Zvekuchengetedza
- 2-Bromo-5-chloro-3-picoline kazhinji haikonzeri kukuvadza kukuru pasi pemamiriro ekushandiswa akajairwa. Zvisinei, zvinogona kutsamwisa maziso, ganda uye kufema turakiti, saka kutarisirwa kunofanira kutorwa kudzivisa zvakananga kubata.
-Shandisa nemidziyo yekudzivirira yakakodzera, senge magirovhosi emakemikari, magirazi uye nhovo dzechiso.
-Maitiro akanaka erabhoritari anofanira kuteverwa panguva yekushandiswa uye mhepo yakanaka inofanira kuchengetedzwa.
-Dzivisa kusangana neakasimba oxidants uye yakasimba acids panguva yekubata nekuchengetedza.
