Hoʻolauna

2-Methylbutyric acid. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka 2-methylbutyric acid:

 

ʻAno maikaʻi:

ʻAno: 2-methylbutyric acid he wai kala ʻole a he aniani paha.

Density: approx. 0.92 g/cm³.

Hiki ke hoʻoheheʻe: 2-methylbutyric acid he ʻāpana i ka wai.

 

E hoʻohana:

Hiki ke hoʻohana ʻia e like me ka solvent no ka resins, plasticizers no plastics, a me nā solvents no ka uhi ʻana.

Hiki ke hoʻohana ʻia ka 2-Methylbutyric acid i ka hoʻomākaukau ʻana i nā mea hoʻopale metala a me nā mea hoʻoheheʻe pena.

 

Hanana:

ʻO nā ʻano hana hoʻomākaukau o ka 2-methylbutyric acid ka mea nui e like me kēia:

Ua hoʻomākaukau ʻia e ka hopena oxidation o ka ethanol.

Hoʻomākaukau ʻia e ka hopena oxidation o 2-methacryrolen.

 

ʻIke palekana:

2-Methylbutyric acid he mea hoʻonāukiuki a hiki ke hoʻoulu i ka huhū a me ka erythema i ka wā e pili ana me ka ʻili, a pono e pale ʻia ka pili pono ʻana me ka ʻili.

ʻO ka inhalation o ka 2-methylbutyric acid vapor e hiki ke hoʻonāukiuki i ka ʻāʻī, ka ʻeha hanu, a me ka ʻū ʻana, a pono e uku ʻia i ka ea a me ka pale pilikino.

I ka wā o ka hoʻohana ʻana, pono e pale ʻia ka hoʻopili ʻana me nā oxidants ikaika a me nā mea puhi ahi i mea e pale ai i nā hopena ʻino.

I ka mālama ʻana a me ka mālama ʻana, pono e pale ʻia ka haʻalulu nui a me nā wela kiʻekiʻe.
