Hoʻolauna

ʻO ka N-butanol, ka mea i kapa ʻia ʻo ka butanol, he mea hoʻohuihui, he wai kala ʻole me kahi ʻala ʻona ʻona. Eia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o n-butanol:

 

ʻAno maikaʻi:

1. Nā waiwai kino: He wai kala ʻole.

2. Nā waiwai kemika: Hiki ke hoʻoheheʻe ʻia i loko o ka wai a me nā mea hoʻoheheʻe organik, a ʻo ia ka hui polar moderately. Hiki ke oxidized i butyraldehyde a me butyric acid, a i ʻole hiki ke hoʻoheheʻe ʻia e hana i ka butene.

 

E hoʻohana:

1. Hoʻohana ʻoihana: He mea hoʻoheheʻe koʻikoʻi ia a he nui nā mea hoʻohana i ka ʻoihana kemika e like me nā uhi, inika, a me nā mea holoi.

2. Ke hoʻohana ʻana i ka Laboratory: Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe no ka hoʻoulu ʻana i ka hoʻopili ʻana i ka protein helical, a hoʻohana pinepine ʻia i nā hoʻokolohua biochemical e catalyze reactions.

 

Hanana:

1. Butylene hydrogenation: Ma hope o ka hoʻoheheʻe ʻana o ka hydrogen, hoʻopili ʻia ka butene me ka hydrogen i mua o kahi catalyst (e like me ka nickel catalyst) e loaʻa ai ka n-butanol.

2. Hoʻoheheʻe wai: hoʻoheheʻe ʻia ka butanol me nā ʻakika ikaika (e like me ka sulfuric acid concentrated) e hoʻohua ai i ka butene ma o ka hoʻoheheʻe ʻana i ka wai, a laila hoʻoheheʻe ʻia ka butene e loaʻa ai ka n-butanol.

 

ʻIke palekana:

1. He wai wela ia, e pale aku i ka pili ana me ke kumu ahi, a e pale aku i ke ahi hamama a me ka wela wela.

3. He mea ʻawaʻawa kona, e pale aku i ka hoʻopili pololei ʻana me ka ʻili a me nā maka, a pale i ka hoʻohu ʻana i kona mahu.

4. I ka wā e mālama ai, pono e mālama ʻia i loko o kahi wahi paʻa, kahi mamao mai nā oxidants a me nā kumu ahi, a mālama ʻia i ka lumi wela.
