Folasaga
3,5-Difluoropyridine o se faʻalapotopotoga faʻapitoa faʻatasi ai ma le vailaʻau vailaʻau C5H3F2N. O lo'o i lalo se fa'amatalaga o lona natura, fa'aoga, fa'atulagaina ma fa'amatalaga saogalemu:
natura:
-Fa'aaliga: vai e leai ni lanu
-Meli liusuavai:-53 ℃
-Puna: 114-116 ℃
-Mōtele: 1.32g/cm³
-Solubility: Solu i le vai ma le tele o solu faʻaola.
Fa'aaogā:
- 3,5-Difluoropyridine e masani ona faʻaaogaina e avea o se mea taua tele i le faʻaogaina o meaola. E mafai ona faʻaaogaina i le tuʻufaʻatasia o vailaʻau faʻamaʻi, vailaʻau ma isi vailaʻau faʻalaʻau.
-E mafai foi ona faʻaaogaina e avea o se vailaʻau vailaʻau mo suʻesuʻega ma suʻesuʻega vailaʻau.
Sauniuniga auala:
O le sauniuniga o le 3,5-Difluoropyridine e masani ona faia e se tasi o metotia nei:
-Amata mai le pyrimidine, muamua faʻafeiloaʻi atoms fluorine i luga o pyrimidine, ona faʻaopoopo lea o atoms fluorine i le 3 ma le 5 tulaga.
-maua mai le 3,5-difluoro chloropyrimidine poʻo le 3,5-difluoro bromopyrimidine reaction.
Fa'amatalaga Saogalemu:
- 3,5-Difluoropyridine atonu e afaina ai le tino o le tagata. O le fa'aalia i le fa'aputuga e ono fa'atupu ai le ita o mata ma le pa'u. O le mea lea, e tatau ona faia ni puipuiga talafeagai, e pei o le ofuina o totigilima talafeagai, mata tioata ma lavalava puipui.
-Pe a paʻi pe manava le 3,5-Difluoropyridine, o le vaega ua afaina e tatau ona faʻamama vave ma fautuaina e se fomaʻi.
-I le taimi o le teuina ma le tagofiaina, e tatau ona faʻaeteete e aloese mai le faʻafesoʻotaʻi ma vailaʻau malolosi ma vailaʻau malolosi.
Faamolemole ia matau pe a faʻaaogaina ma faʻaaogaina le 3,5-Difluoropyridine, ia mulimulitaʻi i taimi uma faʻatonuga o le saogalemu o fale suʻesuʻe ma faʻasino i pepa faʻamatalaga saogalemu ma faʻatonuga.
