Hoʻolauna

ʻO 2-ethoxy-3-methylpyrazine kahi mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: 2-ethoxy-3-methylpyrazine he wai kala ʻole.

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

 

E hoʻohana:

- Hiki ke hoʻohana ʻia i ka synthesis o kekahi mau lāʻau antibiotic (e like me ka polyhydroxysulfamic acid), a me kekahi mau pūhui hana biologically.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka 2-Ethoxy-3-methylpyrazine e ka transesterification o 2-methylpyrazine me ka ethanol. ʻO ke kaʻina hana kikoʻī e pili ana: ka hoʻomehana mua a me ka hoʻoulu ʻana i ka 2-methylpyrazine me ka nui kūpono o ka ethanol i loko o ka reactor, a laila e hoʻohui i kahi nui o ka alkyd catalyst (e like me Fengyun acid), e hoʻomau i ka hoʻomehana ʻana, a hope ka distilling no ka loaʻa ʻana o ka huahana.

 

ʻIke palekana:

- E hoʻohana i nā mea pale kūpono e like me nā mīkina lima lab, nā aniani, a me nā lole pale i ka wā o ke kaʻina hana.
