Hoʻolauna

ʻakika isovaleric. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka isovaleric acid:

 

ʻAno maikaʻi:

Ke ʻano: ʻO ka wai kala ʻole a melemele paha me kahi ala ʻala e like me ka acetic acid.

Māmā: 0.94g/cm³

Hiki ke hoʻoheheʻe ʻia: hiki ke hoʻoheheʻe ʻia me ka ethanol, ether a me nā mea hoʻoheheʻe ʻē aʻe.

 

E hoʻohana:

Synthesis: ʻO ka waika Isovaleric he mea koʻikoʻi kemika synthesis intermediate, i hoʻohana nui ʻia i nā ʻoihana ʻoihana he nui e like me ka synthesis organik, nā lāʻau lapaʻau, nā uhi, nā ʻōpala a me nā plastics.

 

Hanana:

ʻO ke ʻano o ka hoʻomākaukau ʻana o ka waika isovaleric e pili ana i kēia mau ala:

Ma o ka hopena o ka n-butanol, lawe ʻia ka oxidation o ka n-butanol i ka waikona isovaleric me ka hoʻohana ʻana i ka catalyst acid a me ka oxygen.

Hoʻokumu ʻia ka Magnesium butyrate e ka hopena o ka magnesium butyl bromide me carbon dioxide, a laila hoʻololi ʻia i ka waikona isovaleric e ka pane ʻana me ka carbon monoxide.

 

ʻIke palekana:

ʻO ka waika Isovaleric kahi meaʻino, pale i ka piliʻana me kaʻili a me nā maka, a e nānā pono i ka hoʻohanaʻana i nā mīkina lima pale, nā makaaniani palekana a me nā lole pale.

I ka hoʻohana ʻana i ka waikona isovaleric, pono e pale ʻia ka inhalation o kāna mau mahu a pono e hana ʻia ka hana i loko o kahi ʻano maikaʻi.

He haʻahaʻa ka wahi e hoʻā ai, e pale i ka hoʻopili ʻana me ke kumu ahi, a e mālama i kahi mamao mai nā lapalapa a me nā kumu wela.

I ka loaʻa ʻana o ka waika isovaleric, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau.
