Hoʻolauna

ʻO ka 2-Acetyl-3-methylpyrazine kahi hui kūlohelohe. Eia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau, a me ka ʻike palekana o kēia pūhui:

 

ʻAno maikaʻi:

- Ke ʻano: 2-Acetyl-3-methylpyrazine he paʻa ʻole a ʻeleʻele melemele.

- Solubility: He haʻahaʻa kona hiki ke hoʻoheheʻe i ka wai akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik.

 

E hoʻohana:

- Hoʻohana pinepine ʻia ka 2-acetyl-3-methylpyrazine ma ke ʻano he mea waena i ka synthesis kemika. Hiki ke hoʻohana ʻia e like me ka dehydration reagent, cyclization reagent, reducing agent, etc. i ka synthesis organik.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka 2-acetyl-3-methylpyrazine ma ka hana ʻana i ka 2-acetylpyridine me ka methylhydrazine.

- Hiki ke ʻike ʻia ke ʻano hoʻomākaukau kūikawā ma ka palapala e pili ana i ka synthesis kemika organik.

 

ʻIke palekana:

- He mea hoʻonāukiuki paha ka 2-Acetyl-3-methylpyrazine i ka ʻili a me nā maka a pono e holoi ʻia me ka wai nui ma hope koke o ka hoʻopili ʻana.

- I ka hoʻohana ʻana a i ʻole ka hoʻohana ʻana, e pale i ka hanu ʻana i ka lepo a i ʻole ke kinoea. Pono e hana ʻia ma kahi wahi i hoʻoluʻu maikaʻi ʻia.

- I ka wā e mālama ai, pono e mālama ʻia i loko o kahi pahu paʻa i ka ea, ma kahi mamao o nā kumu wela a me nā mea hiki ke puhi ʻia.
