Intangiriro

2,4-Dibromopyridine ni ifumbire mvaruganda. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, uburyo bwo gutegura namakuru yumutekano:

 

Ubwiza:

- Kugaragara: 2,4-dibromopyridine ni ibara ritagira ibara cyangwa ryoroshye rya kristaline ikomeye.

- Gukemura: 2,4-dibromopyridine irashonga mumashanyarazi menshi nka Ethanol, dimethyl sulfoxide na chloroform.

 

Koresha:

- Amabara: Nibisanzwe bikoreshwa mu irangi rishobora gukoreshwa muguhuza amarangi afite amabara atandukanye.

 

Uburyo:

2,4-Dibromopyridine irashobora gutegurwa nuburyo bukurikira:

- Catalyst bromination: Mugihe cya alkaline, 2,4-dibromopyridine irashobora kuboneka mugukora pyridine hamwe na bromine.

- Carbone-deuterium chiral halogenation reaction: 2,4-dibromopyridine iboneka mugukora substrate hamwe na bromine.

 

Amakuru yumutekano:

Umutekano no gukoresha 2,4-dibromopyridine bigomba kubahirizwa hakurikijwe ingingo zikurikira:

- Uru ruganda rufite uburozi kandi rugomba gukoreshwa neza.

- Ibikoresho bikwiye byo kurinda umuntu nka gants, amadarubindi, n imyenda ikingira bigomba kwambara mugihe cyo gukoresha no gukoresha.

- Irinde guhumeka umukungugu wacyo cyangwa guhura nuruhu n'amaso.

- Igomba gukorerwa ahantu hafite umwuka mwiza kandi ikirinda guhura ninkomoko yumuriro kugirango irinde gufata umuriro cyangwa guturika.

- Uburyo bukwiye bwo gukora neza bugomba gukurikizwa mugihe cyo kubika no kubika.
