Intangiriro

2,3-Difluorobenzoic aside ni ifumbire mvaruganda. Ibikurikira ni intangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya acide 2,3-difluorobenzoic:

 

Ubwiza:

- Kugaragara: Ibara ritagira ibara rikomeye

 

Koresha:

 

Uburyo:

- 2,3-Difluorobenzoic aside irashobora gutegurwa na fluorin paraben. Ibikoresho bya fluorine nka hydrofluoric aside na ferrous fluoride bikoreshwa cyane.

 

Amakuru yumutekano:

- Irinde guhura nuruhu, amaso, nibibyimba, hanyuma uhite woza amazi menshi mugihe uhuye.

- Mugihe ubitse kandi ukabitunganya, irinde guhura na okiside na acide zikomeye, kandi wirinde guhura nubushyuhe numuriro.

- Nibiba ngombwa, baza umuhanga mubyimiti kugirango umenye amakuru arambuye yumutekano.

  • Mbere:
  • Ibikurikira:
    • Andika ubutumwa bwawe hano hanyuma utwohereze
