Hoʻolauna

ʻO 2-pentanone, ʻike ʻia hoʻi ʻo pentanone, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2-pentanone:

 

ʻAno maikaʻi:

- Ke ʻano: 2-pentanone he wai kala ʻole me kahi ʻala kūikawā.

- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka wai a hiki ke hui pū me nā mea hoʻoheheʻe organik he nui.

- Hiki ke ahi: 2-pentanone he wai hiki ke ho'āla i ke ahi inā loaʻa ka lapalapa ahi a i ʻole ka wela kiʻekiʻe.

 

E hoʻohana:

- Hoʻohana ʻenehana: Hoʻohana ʻia ʻo 2-pentanone ma ke ʻano he solvent i ka hana ʻana i nā uhi, inks, adhesives, etc., ma ke ʻano he diluent, mea hoʻomaʻemaʻe, a me ka hopena waena.

 

Hanana:

- Hoʻomākaukau ʻia ʻo 2-pentanone ma ka hoʻokahe ʻana i ka pentanol. ʻO ke ʻano maʻamau ka hana ʻana me ka pentanol e kekahi mea hoʻoheheʻe e like me ka oxygen a i ʻole ka hydrogen peroxide, a me ka hoʻokē ʻana i ka hopena e ka catalyst e like me ka potassium chromate a i ʻole ka cerium oxide.

 

ʻIke palekana:

- ʻO ka 2-pentanone ke ahi a pono e mālama ʻia mai nā lapalapa ākea a me nā wela kiʻekiʻe.

- E hoʻohana i nā mīkina lima pale, nā makaaniani pale, a me ka pale alo e pale aku i ka pili ʻana me nā maka, ka ʻili, a me nā mahu.

- Pono e hoʻolei ʻia ka ʻōpala e like me nā kānāwai a me nā hoʻoponopono kūloko, a ʻaʻole pono e hoʻolei ʻia i loko o ka wai a i ʻole ke kaiapuni.

- I ka mālama ʻana a me ka hoʻohana ʻana, e ʻoluʻolu e hahai i nā kaʻina hana palekana kūpono a me nā alakaʻi e hōʻoia i kona hoʻohana pono ʻana a me ka mālama ʻana.
