Intangiriro
2-Bromo-5-nitropyridine ni ifumbire mvaruganda hamwe na formula ya chimique C5H3BrN2O2. Ibikurikira nubusobanuro bwimiterere yabyo, imikoreshereze, imyiteguro namakuru yumutekano:
Kamere:
2-Bromo-5-nitropyridine nikintu cyera gifite uburyohe bwa aside ya oxyde. Ifite ubushyuhe bwinshi nubushyuhe. Gushonga buhoro mumazi mubushyuhe bwicyumba, gushonga mumashanyarazi nka Ethanol na acetone.
Koresha:
2-Bromo-5-nitropyridine ifite uburyo bwinshi bwo gusaba. Nibikoresho byingenzi kandi bigereranijwe muri synthesis. Irashobora gukoreshwa muguhuza imiti yica udukoko, amarangi, ibikoresho bifotora hamwe nibikoresho bya farumasi. Mubyongeyeho, irashobora kandi gukoreshwa nka catalizator na ligand.
Uburyo bwo Gutegura:
2-Uburyo bwa Bromo-5-nitropyridine synthesis nuburyo bukurikira:
1. Na 2-bromopyridine na acide nitricike mubihe bya acide.
2. Na 3-bromopyridine na sodium nitrite reaction mubihe bya alkaline.
Amakuru yumutekano:
2-Bromo-5-nitropyridine ni uburozi bufite ububi bumwe na bumwe. Witondere ingamba z'umutekano zikurikira mugihe cyo gukoresha no kubika:
1. Irinde guhumeka umukungugu cyangwa imyuka, bigomba kuba ahantu hafite umwuka uhagije kugirango ukore.
2. Irinde guhura nuruhu, amaso hamwe nuduce twinshi, nko guhura bigomba guhita byoza n'amazi menshi, hanyuma ugashaka ubufasha bwa muganga.
3. Witondere ingamba zo gukumira umuriro no guturika, irinde guhura nibikoresho byaka.
4. Bika mu kintu gifunze, kure yumuriro na okiside.
5. Kujugunya ukurikije amabwiriza yaho kugirango wirinde gusohora ibidukikije.
Incamake:
2-Bromo-5-nitropyridine ni organic organic hamwe ningingo nyinshi zikoreshwa. Ariko, kubera uburozi bwayo, birakenewe kwitondera imikorere itekanye, kubika neza no kujugunya ibikoresho bisigaye.
