Mawu Oyamba

Propanol, yomwe imadziwikanso kuti isopropanol, ndi organic solvent. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha propanol:

 

Ubwino:

- Propanol ndi madzi opanda mtundu okhala ndi fungo la mowa.

- Imatha kusungunula madzi, ma ether, ma ketoni, ndi zinthu zambiri zachilengedwe.

 

Gwiritsani ntchito:

- Propanol imagwiritsidwa ntchito kwambiri m'makampani ngati chosungunulira popanga utoto, zokutira, zoyeretsa, utoto, ndi utoto.

 

Njira:

- Propanol ikhoza kukonzedwa ndi hydrogenation ya methane hydrates.

- Njira ina yokonzekera yomwe imagwiritsidwa ntchito nthawi zambiri imapezeka ndi hydrogenation mwachindunji ya propylene ndi madzi.

 

Zambiri Zachitetezo:

- Propanol ndi yoyaka ndipo iyenera kusungidwa kutali ndi moto wotseguka komanso kutentha kwambiri.

- Pogwira ntchito ya propanol, valani zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zovala zodzitetezera.
