Intangiriro
3,5-Difluoropyridine ni ifumbire mvaruganda hamwe na chimique C5H3F2N. Ibikurikira nubusobanuro bwimiterere yabyo, imikoreshereze, imiterere namakuru yumutekano:
Kamere:
-Ibigaragara: amazi adafite ibara
-Gushonga ingingo: -53 ℃
-Ibintu bitetse: 114-116 ℃
-Ubucucike: 1.32g / cm³
-Gukemuka: Gushonga mumazi hamwe na solge nyinshi.
Koresha:
- 3,5-Difluoropyridine ikoreshwa cyane nkibikoresho byingenzi muri synthesis. Irashobora gukoreshwa muguhuza imiti yica udukoko, imiti nibindi bintu kama.
-Bishobora kandi gukoreshwa nka reagent ya chimique yo gusesengura nubushakashatsi bwimiti.
Uburyo bwo Gutegura:
Gutegura 3,5-Difluoropyridine mubusanzwe bikorwa nuburyo bumwe bukurikira:
-Uhereye kuri pyrimidine, banza winjize atome ya fluor kuri pyrimidine, hanyuma wongeremo atome ya fluor kumwanya wa 3 na 5.
-yakiriwe kuva 3,5-difluoro chloropyrimidine cyangwa 3,5-difluoro bromopyrimidine reaction.
Amakuru yumutekano:
- 3,5-Difluoropyridine irashobora kwangiza umubiri wumuntu. Guhura nuruvange bishobora gutera amaso hamwe nuruhu kurwara. Niyo mpamvu, birakenewe gufata ingamba zikenewe zo gukingira, nko kwambara uturindantoki dukwiye, indorerwamo n’imyambaro ikingira.
-Iyo gukoraho cyangwa guhumeka 3,5-Difluoropyridine, ahantu hafashwe hagomba guhita hasukurwa kandi bikagirwa inama na muganga.
-Mu gihe cyo kubika no gutunganya, hagomba kwitonderwa kugirango wirinde guhura na okiside ikomeye na acide zikomeye.
Nyamuneka menya ko mugihe ukoresha no gukoresha 3,5-Difluoropyridine, burigihe ukurikize inzira zumutekano za laboratoire hanyuma ukoreshe urupapuro rwumutekano hamwe namabwiriza.
