Isingeniso

I-2-Acetyl-3-methylpyrazine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela, kanye nolwazi lokuphepha lwale nhlanganisela:

 

Ikhwalithi:

- Ukubukeka: I-2-Acetyl-3-methylpyrazine iqinile engenambala ukuya kokuphuzi okuphaphathekile.

- Ukunyibilika: Ine-solubility ephansi emanzini kodwa ingancibilika kuzincibilikisi zemvelo.

 

Sebenzisa:

- I-2-acetyl-3-methylpyrazine ivame ukusetshenziswa njengendawo ephakathi ekuhlanganiseni kwamakhemikhali. Ingasetshenziswa njenge-reagent yokuphelelwa amanzi emzimbeni, i-cyclization reagent, i-ejenti yokunciphisa, njll ku-organic synthesis.

 

Indlela:

- I-2-acetyl-3-methylpyrazine ingalungiswa ngokuphendula i-2-acetylpyridine nge-methylhydrazine.

- Indlela ethize yokulungiselela ingatholakala ezincwadini eziphathelene nokuhlanganiswa kwamakhemikhali aphilayo.

 

Ulwazi Lokuphepha:

- I-2-Acetyl-3-methylpyrazine ingase ichithe isikhumba namehlo futhi kufanele ihlanzwe ngamanzi amaningi ngokushesha ngemva kokuthintana.

- Uma usebenzisa noma ubamba, gwema ukuhogela uthuli noma amagesi. Kufanele isetshenziswe endaweni enomoya omuhle.

- Uma uyigcina, kufanele igcinwe esitsheni esingangeni moya, kude nemithombo yokushisa nezinto ezivuthayo.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
