Intangiriro

4-Acide Methylvaleric, izwi kandi nka acide isovaleric, ni ifumbire mvaruganda. Ibikurikira nintangiriro ngufi kumiterere yabyo, imikoreshereze, uburyo bwo gutegura namakuru yumutekano:

 

Ubwiza:

- Kugaragara: Amazi adafite ibara

- Gukemura: Kubora mumazi no kumashanyarazi

- Impumuro: Ifite impumuro nziza isa na acide acike

 

Koresha:

- Mu nganda zihumura neza, irashobora gukoreshwa muguhuza uburyohe bwimbuto, imboga n ibirungo.

- Mu nganda zitwikiriye, zikoreshwa nka solge na plastike.

 

Uburyo:

- 4-Methylpentanoic aside irashobora gutegurwa nigisubizo cya acide isovaleric na monoxyde de carbone imbere yumucyo.

- Catalizator nka aside ya aluminique cyangwa karubone ya potasiyumu ikoreshwa mugukora reaction.

 

Amakuru yumutekano:

- 4-Methylpentanoic aside ni amazi yaka kandi agomba kubikwa kure yumuriro nubushyuhe bwinshi.

- Kwambara ibikoresho bikingira, nka gants no kurinda amaso, mugihe ukoresheje.

- Irinde guhumeka, kuribwa, cyangwa guhura nuruhu n'amaso mugihe ukora.
