Intangiriro

Inzoga ya Isoamyl, izwi kandi ku izina rya isobutanol, ifite imiti ya C5H12O. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, uburyo bwo gutegura namakuru yumutekano:

 

Ubwiza:

1. Inzoga ya Isoamyl ni amazi atagira ibara hamwe na vino idasanzwe.

2. Ifite aho itetse ya 131-132 ° C hamwe n'ubucucike bwa 0,809g / mLat 25 ° C (lit.).

3. Inzoga ya Isoamyl irashonga mumazi hamwe na solge nyinshi.

 

Koresha:

1.

2. Inzoga ya Isoamyl irashobora kandi gukoreshwa muguhuza ibindi bintu nka ethers, esters, na aldehydes na ketone.

 

Uburyo:

1.

2. Ubundi buryo bwo gutegura buboneka hamwe na hydrogenation ya isobutylene.

 

Amakuru yumutekano:

1. Inzoga ya Isoamyl ni amazi yaka umuriro ashobora gutera umuriro mugihe ahuye ninkomoko.

2. Iyo ukoresheje inzoga isoamyl, birakenewe kwirinda guhumeka, guhura nuruhu cyangwa kwinjira mumubiri kugirango wirinde kwangiza ubuzima.

3. Hagomba gufatwa ingamba nziza zo guhumeka mugihe ukoresheje inzoga isoamyl kugirango umwuka wimbere mu nzu.

4. Mugihe cyo kumeneka, inzoga ya isoamyl igomba kwigunga vuba, kandi imyanda igomba gutabwa neza kugirango birinde kwitwara nibindi bintu.
