Okwu mmalite
3,5-Difluoropyridine bụ ngwakọta organic na usoro kemịkalụ C5H3F2N. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nhazi ya na ozi nchekwa:
Ọdịdị:
- Ọdịdị: mmiri mmiri na-enweghị agba
- Ebe mgbaze:-53 ℃
- Ebe esi mmiri: 114-116 ℃
-Njupụta: 1.32g/cm³
-Solubility: Soluble na mmiri na ọtụtụ ihe mgbaze organic.
Jiri:
- 3,5-Difluoropyridine bụ nke a na-ejikarị eme ihe dị ka ihe dị mkpa na nhazi nke organic. Enwere ike iji ya na njikọ nke pesticides, pharmaceuticals na ndị ọzọ organic ogige.
-Enwekwara ike iji ya dị ka ihe reagent maka nyocha na nyocha kemịkalụ.
Ụzọ nkwadebe:
A na-eme nkwadebe nke 3,5-Difluoropyridine site na otu n'ime ụzọ ndị a:
Malite site na pyrimidine, buru ụzọ webata atom fluorine na pyrimidine, wee tinye atom fluorine na ọnọdụ 3 na 5.
enwetara site na 3,5-difluoro chloropyrimidine ma ọ bụ 3,5-difluoro bromopyrimidine mmeghachi omume.
Ozi nchekwa:
-3,5-Difluoropyridine nwere ike imerụ ahụ mmadụ. Mkpughe na ogige ahụ nwere ike ịkpata mmeghachi omume iwe na anya na akpụkpọ ahụ. Ya mere, ọ dị mkpa ịme ihe nchebe dị mkpa, dị ka iyi uwe aka kwesịrị ekwesị, enyo na uwe nchebe.
-Mgbe ị na-emetụ ma ọ bụ na-eku ume 3,5-Difluoropyridine, a ga-ehichapụ ebe ahụ emetụtara ozugbo ma nye ndụmọdụ dọkịta.
-N'oge nchekwa na njikwa, ekwesịrị ịkpachara anya iji zere kọntaktị na oxidants siri ike na acid siri ike.
Biko mara na mgbe ị na-eji ma na-ejikwa 3,5-Difluoropyridine, na-agbaso usoro nchekwa ụlọ nyocha mgbe niile ma rụtụ aka na mpempe akwụkwọ nchekwa data dị mkpa na ntuziaka.
