Nhanganyaya
3,5-Difluoropyridine is organic compound ine kemikari formula C5H3F2N. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzira uye ruzivo rwekuchengetedza:
Zvakasikwa:
-Kuonekwa: mvura isina ruvara
-Kunyungudika: -53 ℃
-Kubikira poindi: 114-116 ℃
-Density: 1.32g/cm³
-Solubility: Soluble mumvura uye yakawanda organic solvents.
Shandisa:
- 3,5-Difluoropyridine inonyanya kushandiswa sechinhu chakakosha chakasvibirira mune organic synthesis. Inogona kushandiswa mukugadzirwa kwemishonga yezvipembenene, mishonga uye mamwe organic compounds.
-Inogonawo kushandiswa sekemikari reagent yekuongorora uye tsvakurudzo yemakemikari.
Kugadzirira nzira:
Kugadzirira kwe3,5-Difluoropyridine kunowanzoitwa neimwe yeiyi nzira dzinotevera:
-Kutanga kubva papyrimidine, tanga waisa maatomu efluorine papyrimidine, wozowedzera maatomu efluorine kune 3 uye 5 nzvimbo.
-yakawanikwa kubva ku3,5-difluoro chloropyrimidine kana 3,5-difluoro bromopyrimidine reaction.
Zvekuchengetedza
- 3,5-Difluoropyridine inogona kukuvadza muviri wemunhu. Kusangana nekomboni kunogona kukonzera kushatirwa kwemaziso neganda. Naizvozvo, zvinodikanwa kutora matanho ekudzivirira anodiwa, sekupfeka magirovhosi akakodzera, magirazi uye zvipfeko zvekudzivirira.
-Kana uchibata kana kufema 3,5-Difluoropyridine, nzvimbo yakakanganiswa inofanira kucheneswa pakarepo uye inorayirwa nachiremba.
-Panguva yekuchengetedza nekubata, kutarisirwa kunofanira kutorwa kuti usasangana neakasimba oxidants uye yakasimba acids.
Ndokumbira utarise kuti kana uchishandisa uye kubata 3,5-Difluoropyridine, gara uchitevera nzira dzakakodzera dzekuchengetedza marabhoritari uye utarise kune akakodzera kuchengetedza data mapepa nemirayiridzo.
