Intangiriro

Propanol, izwi kandi nka isopropanol, ni umusemburo kama. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya propanol:

 

Ubwiza:

- Propanol ni amazi atagira ibara hamwe numunuko uranga alcool.

- Irashobora gushonga amazi, ethers, ketone, nibintu byinshi kama.

 

Koresha:

- Propanol ikoreshwa cyane mu nganda nkigisubizo cyo gukora amarangi, impuzu, ibikoresho byoza, amarangi, hamwe na pigment.

 

Uburyo:

- Propanol irashobora gutegurwa na hydrogenation ya metani hydrat.

- Ubundi buryo bukoreshwa muburyo bwo gutegura buboneka hakoreshejwe hydrogenation itaziguye ya propylene namazi.

 

Amakuru yumutekano:

- Propanol irashya kandi igomba kubikwa kure yumuriro nubushyuhe bwinshi.

- Mugihe ukoresha propanol, ambara ibikoresho bikingira birinda nka gants, indorerwamo, n imyenda ikingira.
