Intangiriro

acide formic) ni amazi atagira ibara afite impumuro mbi. Ibikurikira nibintu nyamukuru bya aside irike:

 

Imiterere yumubiri: Acide formike irashonga cyane kandi igashonga mumazi hamwe na solge nyinshi.

 

Imiterere ya chimique: Acide formique nigikoresho kigabanya okiside byoroshye kuri dioxyde de carbone namazi. Urusobekerane rufite ishingiro rikomeye kugirango rutange formate.

 

Imikoreshereze nyamukuru ya acide formique niyi ikurikira:

 

Nka disinfectant and preservative, aside formic irashobora gukoreshwa mugutegura amarangi nimpu.

 

Acide ya formic irashobora kandi gukoreshwa nkigikoresho cyo gushonga urubura na mite yica.

 

Hariho uburyo bubiri bwingenzi bwo gutegura aside irike:

 

Uburyo gakondo: Uburyo bwo gusibanganya kubyara aside irike ukoresheje okiside igice cyibiti.

 

Uburyo bugezweho: aside formike itegurwa na okiside ya methanol.

 

Icyitonderwa cyo gukoresha neza aside ya formic nuburyo bukurikira:

 

Acide ya formique ifite impumuro nziza kandi yangirika, ugomba rero kwambara uturindantoki twirinda hamwe nikirahure mugihe uyikoresheje.

 

Irinde guhumeka umwuka wa acide cyangwa ivumbi, kandi urebe neza ko uhumeka neza mugihe ukoresheje.

 

Acide formique irashobora gutera inkongi kandi igomba kubikwa kure yumuriro nibikoresho byaka.
