Hoʻolauna

ʻO 3-hydroxy-2-butanone, i kapa ʻia ʻo butyl ketone acetate a i ʻole butyl acetate ether, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 3-hydroxy-2-butanone:

 

ʻAno maikaʻi:

- Ke ʻano: 3-Hydroxy-2-butanone he wai kala ʻole.

- Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai a me ka hapa nui o nā mea hoʻoheheʻe organik.

 

E hoʻohana:

- Hoʻohui kemika: hiki ke hoʻohana ʻia ka 3-hydroxy-2-butanone ma ke ʻano he reagent i ka synthesis organik a hoʻokani i ka hana o kahi hui ester i kekahi mau hopena.

 

Hanana:

- Hiki ke hoʻopili ʻia ka 3-Hydroxy-2-butanone me ka hydrogen peroxide e ka butyl acetate e loaʻa ai ka hydroxyketone pili.

 

ʻIke palekana:

- 3-Hydroxy-2-butanone he haʻahaʻa koʻikoʻi ma lalo o nā kūlana maʻamau o ka hoʻohana ʻana, akā pono e hoʻohana ʻia me ka akahele.

- ʻO ka hoʻolaha ʻana i ka 3-hydroxy-2-butanone hiki ke hōʻeha i ka maka a me ka ʻili, a pono e pale ʻia ka pilina pololei.

- I ka hoʻohana ʻana i ka 3-hydroxy-2-butanone, pono e mālama pono i ka hana palekana me ka ea kūpono a me ka hoʻohana ʻana i nā lako pale pilikino.
