Isingeniso

I-2-acetylpyrazine iyinhlanganisela yezinto eziphilayo. Inokunambitheka nephunga elifana nesinkwa esibhakiwe noma ukudla okuthosiwe. Okulandelayo isingeniso esiningiliziwe sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-acetylpyrazine:

Ikhwalithi:

- Ukubukeka: I-2-acetylpyrazine iwuketshezi olungenambala noma oluphuzi olunephunga elihlukile.

- I-Solubility: Incibilika otshwaleni, i-ketone ne-ether solvents, ayincibiliki emanzini.

Sebenzisa:

Indlela:

Kunezindlela eziningana zokulungiselela i-2-acetylpyrazine:

- Kutholwe ekuphenduleni kwe-1,4-diacetylbenzene ne-hydrazine.

- Kutholwe ngokuncishiswa kwe-catalytic kwe-2-acetyl-3-methoxypyrazine ne-hydrogen.

Ulwazi Lokuphepha:

- Gwema ukuthinta isikhumba namehlo, futhi gqoka amagilavu nezibuko lapho usebenzisa.

- Gwema ukuhogela umhwamuko wayo futhi usebenze endaweni engenawo umoya.

- Lapho uyigcina, kufanele igcinwe ivalwe ngokuqinile, kude nomlilo nama-oxidants.
