Intangiriro

N-butanol, izwi kandi nka butanol, ni ifumbire mvaruganda, ni amazi atagira ibara afite impumuro idasanzwe ya alcool. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya n-butanol:

 

Ubwiza:

1. Ibintu bifatika: Nibintu bitagira ibara.

2. Imiterere yimiti: Irashobora gushonga mumazi no mumashanyarazi kama, kandi nikintu kiringaniye. Irashobora kuba okiside kuri butyraldehyde na acide butyric, cyangwa irashobora kubura umwuma kugirango ikore butene.

 

Koresha:

1.

2.

 

Uburyo:

1.

.

 

Amakuru yumutekano:

1.Ni amazi yaka umuriro, irinde guhura ninkomoko yumuriro, kandi wirinde umuriro ugurumana hamwe nubushyuhe bwo hejuru.

3. Ifite uburozi runaka, irinde guhura nuruhu n'amaso, kandi wirinde guhumeka umwuka wacyo.

4. Iyo ubitse, igomba kubikwa ahantu hafunze, kure ya okiside n’amasoko yumuriro, kandi ikabikwa mubushyuhe bwicyumba.
