Okwu mmalite
2,3-dibromo-5-methylpyridine (2,3-dibromo-5-methylpyridine) bụ ngwakọta organic na usoro kemịkalụ C6H5Br2N. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nkwadebe na ozi nchekwa ya:
Ọdịdị:
2,3-dibromo-5-methylpyridine bụ odo siri ike nke nwere isi ísì. Ọ nwere ebe mgbaze nke ihe dịka 63-65 degrees Celsius na ebe isi ihe dị ka 269-271 Celsius. Ọ na-esighi ike na mmiri na soluble na organic solvents.
Jiri:
2,3-dibromo-5-methylpyridine bụ ihe na-emekọrịta ihe n'etiti. Enwere ike iji ya na-emepụta ogige ndị ọzọ dị ndụ, dị ka ihe ndị na-emepụta ihe na-arụ ọrụ ndụ, ọgwụ na pesticides. A pụkwara iji ya mee ihe maka njikọ ihe onwunwe nke ngwaọrụ eletrọnịkị dị ka organic ìhè-emitting diodes (OLED) na organic batrị.
Usoro:
Enwere ike nweta 2,3-dibromo-5-methylpyrridine site na imeghachi 5-methylpyridine na bromine. 5-Methylpyridine na-ebu ụzọ meghachi omume na hydrogen bromide, wee gaa n'ihu na-emeghachi omume na methyl chloride n'ihu onye na-emepụta ihe iji mepụta ngwaahịa ezubere iche.
Ozi nchekwa:
2,3-dibromo-5-methylpyrridine na-akpasu iwe ma nwee ike ịkpasu anya, akpụkpọ ahụ na usoro iku ume. N'oge a na-eji ya eme ihe, a ga-ahụrịrị usoro ọrụ nchekwa nke ọma, a ga-ezere kọntaktị ozugbo na akpụkpọ ahụ na anya, ma hụ na a ga-arụ ọrụ ahụ na ebe ikuku na-ekpo ọkụ. N'oge njikwa na nchekwa, ekwesịrị ịkpachara anya iji zere kọntaktị na oxidants na ihe ndị na-ere ọkụ iji gbochie ihe ize ndụ nke ọkụ na mgbawa. Ọ bụrụ na ikuru ume ma ọ bụ kpughee na ogige a, chọọ ndụmọdụ ahụike ozugbo wee kpọtụrụ dọkịta ọkachamara.
