Taw qhia

Propanol, tseem hu ua isopropanol, yog cov organic hnyav. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm propanol:

 

Zoo:

- Propanol yog cov kua tsis muaj xim nrog cov yam ntxwv tsw ntawm cawv.

- Nws tuaj yeem yaj dej, ethers, ketones, thiab ntau yam organic.

 

Siv:

- Propanol yog siv dav hauv kev lag luam los ua cov kuab tshuaj hauv kev tsim cov xim, coatings, tshuaj ntxuav, dyes, thiab pigments.

 

Txoj kev:

- Propanol tuaj yeem npaj los ntawm hydrogenation ntawm methane hydrates.

- Lwm txoj kev npaj siv feem ntau yog tau los ntawm kev ncaj qha hydrogenation ntawm propylene thiab dej.

 

Cov ntaub ntawv kev nyab xeeb:

- Propanol yog flammable thiab yuav tsum tau ceev kom deb ntawm qhov qhib nplaim taws thiab kub kub.

- Thaum tuav propanol, hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv.
