Okwu mmalite
3,5-Dibromo-2-fluoropyridine bụ ngwakọta organic nke nwere usoro kemịkalụ C5H2Br2FN. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nhazi ya na ozi nchekwa:
Ọdịdị:
- 3,5-Dibromo-2-fluoropyridine bụ ngwakọta siri ike nke nwere ọdịdị kristal na-acha ọcha.
Ebe agbaze ya bụ 74-76 ℃, ebe isi ya bụ 238-240 ℃.
-Ọ bụ ihe a na-adịghị ahụkebe na mmiri n'ime ụlọ okpomọkụ, ma enwere ike ịgbaze ya na ụfọdụ ihe mgbaze organic dị ka ether na ethanol.
Jiri:
- 3,5-Dibromo-2-fluoropyridine bụ ihe dị n'etiti etiti a na-ejikarị eme ihe na mmeghachi omume nke organic.
- Enwere ike iji ya dị ka ihe eji eme ihe maka ihe ndị na-emepụta fotovoltaic organic, a pụkwara iji ya kwadebe ọgwụ, ihe na-esiji na pesticides.
Ụzọ nkwadebe:
- 3,5-Dibromo-2-fluoropyridine nwere ike ịkwado site na mmeghachi omume nke pyridine iodide na cuprous bromide.
- Mbụ gbazee cuprous bromide na pyridine iodide na dimethyl sulfoxide na ụlọ okpomọkụ na-etolite a reactant, wee jiri nwayọọ nwayọọ tinye silver fluoride dropwise na obere okpomọkụ, na n'ikpeazụ okpomọkụ ruo mgbe mmeghachi omume agwụla.
Ozi nchekwa:
- 3,5-Dibromo-2-fluoropyridine na-akpasu iwe na akpụkpọ ahụ na anya, na ihe nchebe kwesịrị ilebara anya mgbe ị na-akpakọrịta.
-Lezienụ anya na ikuku ikuku dị mma mgbe ị na-eji ogige a.
-Ọ na-agbaze na okpomọkụ dị elu ga-emepụta gas na-emerụ ahụ, ọ dịkwa mkpa iji zere ikpughe ọkụ na-emeghe ma ọ bụ ọnọdụ okpomọkụ dị elu.
- Chekwaa ya n'ụzọ mkpuchi ma zere kọntaktị na oxidants na acid siri ike iji zere mmeghachi omume dị ize ndụ.
