2 5-dibromo-6-methylpyridine (CAS#)39919-65-8) Okwu mmalite
2,5-Dibromo-6-methylpyridine bụ ngwakọta organic. Ndị a bụ mmalite nke akụrụngwa ya, ojiji ya, ụzọ nkwadebe na ozi nchekwa:
Njirimara:
Ọdịdị: 2,5-Dibromo-6-methylpyridine bụ ihe siri ike na-acha odo odo na-enweghị agba.
Solubility: Ọ na-agbaze na ụfọdụ ihe mgbaze organic, dị ka ethanol, ether na ester solvents.
Na-eji: Enwere ike iji ya na njikọ organic iji webata otu methyl ma ọ bụ dị ka bromination reagent.
Usoro nkwadebe:
Enwere ike ịme usoro nkwadebe nke 2,5-Dibromo-6-methylpyridine site na usoro ndị a:
Gbarie 2,6-dimethylpyridine na mmanya, ketone ma ọ bụ ihe mgbaze ester.
Tinye bromine ma ọ bụ bromination reagent na ngwọta mmeghachi omume.
A na-eme mmeghachi omume na okpomọkụ kwesịrị ekwesị, na oge mmeghachi omume na-adịkarị ogologo.
Mgbe ị nwetasịrị ngwaahịa ahụ, enwere ike ịwepụta ya ma mee ka ọ dị ọcha site na distillation ma ọ bụ ụzọ nchacha kristal.
Ozi nchekwa:
2,5-Dibromo-6-methylpyridine na-egbu egbu ruo n'ókè ụfọdụ ma kpasuo akpụkpọ ahụ na anya iwe. Ekwesịrị izere kọntaktị ozugbo. Mgbe a na-arụ ọrụ, a ga-eyi ihe nchebe kwesịrị ekwesị, dị ka uwe aka na anya. Ekwesịrị ịrụ ọrụ na mpaghara ikuku nke ọma iji gbochie iku ume nke gas na-emerụ ahụ. Mgbe ị na-ekpofu ihe mkpofu, a ga-edozi ya dịka iwu obodo siri dị. Mgbe ị na-eji ma ọ bụ na-echekwa 2,5-dibromo-6-methylpyridine, ekwesịrị ịkpachara anya iji zere ọkụ na oke okpomọkụ.
