Hoʻolauna

ʻO ka propanol, i kapa ʻia ʻo isopropanol, he mea hoʻoheheʻe organik. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o propanol:

 

ʻAno maikaʻi:

- He wai waihoʻoluʻu ʻole ka propanol me ke ʻano ʻala o nā ʻona.

- Hiki iā ia ke hoʻoheheʻe i ka wai, nā ethers, nā ketones, a me nā mea kūlohelohe he nui.

 

E hoʻohana:

- Hoʻohana nui ʻia ʻo Propanol i ka ʻoihana ma ke ʻano he mea hoʻoheheʻe i ka hana ʻana i nā pena, nā uhi, nā mea hoʻomaʻemaʻe, nā mea ʻulaʻula, a me nā puaʻa.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka propanol e ka hydrogenation o ka methane hydrates.

- Loaʻa kekahi ʻano hoʻomākaukau maʻamau e ka hydrogenation pololei o propylene a me ka wai.

 

ʻIke palekana:

- He mea lapalapa ka propanol a pono e mālama ʻia mai nā lapalapa ākea a me nā wela kiʻekiʻe.

- I ka lawelawe ʻana i ka propanol, e hoʻokomo i nā mea pale kūpono e like me nā mīkina lima, nā maka aniani, a me nā lole pale.
