Intshayelelo

I-2-acetylpyrazine yi-organic compound. Inencasa kunye nevumba elifana nesonka esibhakiweyo okanye ukutya okuqhotsiweyo. Oku kulandelayo kukwaziswa okucacileyo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2-acetylpyrazine:

Umgangatho:

- Imbonakalo: I-2-acetylpyrazine ngulwelo olungenambala okanye olutyheli kunye nevumba elahlukileyo.

- Ukunyibilika: Ukunyibilika etywaleni, iketone kunye nezinyibilikisi ze-ether, ezinganyibilikiyo emanzini.

Sebenzisa:

Indlela:

Kukho iindlela ezininzi zokulungiselela i-2-acetylpyrazine:

- Ifunyenwe kwi-reaction ye-1,4-diacetylbenzene kunye ne-hydrazine.

- Ifunyenwe ngokunciphisa i-catalytic ye-2-acetyl-3-methoxypyrazine kunye ne-hydrogen.

Ulwazi ngoKhuseleko:

• Kuphephe ukudibana nolusu kunye namehlo, kwaye unxibe iiglavu kunye nezibuko xa usebenzisa.

• Kuphephe ukuphefumla umphunga kwaye usebenze kwindawo engena umoya.

- Xa ugcina, kufuneka igcinwe ivalwe ngokuqinileyo, kude nomlilo kunye ne-oxidants.
