Hoʻolauna

ʻO 2,3-hexanedione (ʻike pū ʻia ʻo pentanedione-2,3) he mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2,3-hexanedione:

 

ʻAno maikaʻi:

- Ke ʻano: 2,3-hexanedione he paʻa kala kala ʻole.

- Ka hoʻoheheʻe ʻia: Hiki ke hoʻoheheʻe ʻia i loko o ka wai a ʻoi aku ka hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā waiʻona, eter a me nā hydrocarbons.

- Polarity: He pūhui polar hiki ke hana i nā paʻa hydrogen.

 

E hoʻohana:

- Nā noi ʻoihana: hiki ke hoʻohana ʻia ka 2,3-hexanedione ma ke ʻano he solvent, catalyst a me ke kemika waena.

- Hoʻohui kemika: Hoʻohana pinepine ʻia ia ma ke ʻano he kumu waiwai nui i ka synthesis organik a hiki ke hoʻohana ʻia e synthesize i nā ketones, nā waikawa, a me nā mea hoʻohui ʻē aʻe.

 

Hanana:

- Ke ala oxidation: hiki ke hoʻomākaukau ʻia ka 2,3-hexanedione e ka hopena oxidation o n-octanol. Hoʻohana pinepine ʻia nā mea oxidizing e like me ka oxygen carbonate a me ka acid hydrogen peroxide i ka hopena.

- Nā ala synthetic ʻē aʻe: 2,3-hexanedione, e like me ka oxidene a i ʻole oxanal, hiki ke hoʻomākaukau ʻia e nā ʻano hana synthesis ʻē aʻe.

 

ʻIke palekana:

- 2,3-Hexanedione he mea hoʻonāukiuki i nā maka a me kaʻili a pono e paleʻia i ka pilina pololei.

- E hoʻohana i nā mea pale kūpono e like me nā mīkina lima, nā maka aniani, a me nā lole lab ke hoʻohana a lawelawe paha i ka 2,3-hexanedione.

- Pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants i ka wā e mālama ai a mālama i ka 2,3-hexanedione e pale ai i ke ahi a pahū paha.

- Hoʻopau ʻōpala: E hoʻolei i ka ʻōpala 2,3-hexanedione me ka palekana e like me nā lula kūloko e pale i ke kaiapuni.
