Okwu mmalite
2-Bromo-5-chloro-3-picoline bụ ngwakọta organic nwere usoro kemịkalụ C7H6BrClN. Nke a bụ nkọwa nke njirimara, ojiji, nkwadebe na ozi nchekwa nke ogige ahụ:
Ọdịdị:
-ọdịdị: 2-Bromo-5-chloro-3-picoline bụ mmiri mmiri na-enweghị agba ma ọ bụ ntakịrị odo odo.
-Solubility: Soluble n'ọtụtụ ihe mgbaze organic, dị ka ethanol, dimethylformamide na chloroform.
- Ebe na-agbaze na ebe a na-esi nri: Ebe mgbaze nke ogige ahụ dị ihe dịka -35 ° C, ebe a na-esi ísì bụ ihe dịka 205-210 ° C.
Jiri:
- 2-Bromo-5-chloro-3-picoline nwere ike iji dị ka ihe mmalite ma ọ bụ etiti na njikọ organic, a pụkwara iji ya mee ihe na-emepụta ogige ndị ọzọ, dị ka pesticides na ọgwụ ọjọọ.
-A na-ejikwa ya na intermediates sịntetik, polychlorinated biphenyls, polybrominated biphenyls na pigmenti.
Ụzọ nkwadebe:
- 2-Bromo-5-chloro-3-picoline na-akwadokarị site na bromination na chlorination nke 3-picoline. Nke mbụ, 3-methylpyridine na-emeghachi omume na hydrogen bromide iji nweta 2-bromo-5-methylpyridine, mgbe ahụ, a na-emeghachi ngwaahịa ahụ na metal chloride catalyst iji nweta ngwaahịa ezubere iche.
Ozi nchekwa:
- 2-Bromo-5-chloro-3-picoline n'ozuzu anaghị akpata nnukwu mmerụ ahụ n'okpuru ọnọdụ ojiji nkịtị. Otú ọ dị, ọ nwere ike na-akpasu anya, akpụkpọ ahụ na akụkụ iku ume, ya mere ekwesịrị ịkpachara anya ka ịzere kọntaktị ozugbo.
-Jiri ngwa nchebe kwesịrị ekwesị, dị ka uwe kemịkalụ, enyo na ọta ihu.
-Ekwesịrị ịgbaso usoro nyocha ụlọ nyocha dị mma mgbe a na-eji ya na ikuku ikuku dị mma.
- Zere kọntaktị na oxidants siri ike na acid siri ike n'oge njikwa na nchekwa.
