Hoʻolauna

ʻO ka waika N-valeric, ʻike ʻia hoʻi ʻo valeric acid, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka n-valeric acid:

 

ʻAno maikaʻi:

N-valeric acid he wai waihoʻoluʻu me ka ʻono hua a hiki ke hoʻoheheʻe ʻia i ka wai.

 

E hoʻohana:

He ʻokoʻa ka hoʻohana ʻana o ka waikawa N-valeric i ka ʻoihana. ʻO kekahi noi nui he mea hoʻoheheʻe i nā ʻoihana e like me nā uhi, dyes, adhesives, etc.

 

Hanana:

Hiki ke hoʻomākaukau ʻia ka waika Valeric e nā ʻano hana maʻamau ʻelua. ʻO kekahi ʻano hana, ʻo ia ka hoʻoheheʻe ʻana i ka pentanol a me ka oxygen i mua o kahi mea hoʻoheheʻe e hana ai i ka waikawa n-valeric. ʻO kekahi ala ʻē aʻe ʻo ka hoʻomākaukau ʻana i ka waikawa n-valeric ma o ka hoʻokahe ʻana i ka 1,3-butanediol a i ʻole 1,4-butanediol me ka oxygen i mua o kahi catalyst.

 

ʻIke palekana:

He wai wela ka Norvaleric acid a pono e mālama ʻia mai nā lapalapa a me nā kumu wela. I ka lawelawe ʻana a me ka hoʻohana ʻana, pono e lawe i nā mea palekana e pono ai, e like me ke komo ʻana i nā aniani pale, nā mīkina lima a me nā lole pale. Pono e mālama ʻia ka ʻakika N-valeric i loko o kahi pahu paʻa i ka ea, ma kahi mamao aku i nā mea ʻona a me nā meaʻai. Pono e mālama i ka mālama ʻana a me ka hoʻohana ʻana e pale aku i ka pane ʻana me nā kemika ʻē aʻe.
