Hoʻolauna

ʻO 2-Methoxy-3-methylpyrazine (ʻike pū ʻia me ka methoxylate) he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: ʻO Melafenone kahi kala ʻole i ka aniani melemele māmā a i ʻole ka pauka crystalline.

- Solubility: ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol a me ka chloroform.

 

E hoʻohana:

 

Hanana:

Nui nā ʻano e hoʻomākaukau ai i ka melafenone, a ʻo nā mea maʻamau e komo i kēia mau mea ʻelua:

- Hoʻohui ʻia e ka hopena oxidation: Hoʻopili ʻia ka 2-methoxy-3-methylpyridine me ka zinc chloride, a laila hoʻokaʻawale ʻia me ka waikawa e loaʻa ai ka methrafenone.

- Hoʻohui ʻia e ka pane hoʻololi: Hoʻopili ʻia ka Methoxy-3-methylpyridine me kahi mea pani (e like me ka methyl iodide) ma lalo o ka catalysis alkali e loaʻa ai ka methrenone.

 

ʻIke palekana:

- He kemika ka Melafenone a loaʻa kekahi mau pōʻino.

- Hōʻalo i ka hanu ʻana i ka lepo, pili me ka ʻili a me nā maka, a pale i ka ʻai ʻana.

- E hoʻohana i nā mīkina lima pale a me nā aniani e hōʻoia i ka maikaʻi o ka ea.

- Pono e hoʻolei ʻia ka ʻōpala e like me nā kānāwai kaiapuni kūloko.
