Intshayelelo
I-2-Ethylpyrazine yi-organic compound. Oku kulandelayo yintshayelelo kwezinye iimpawu zekhompawundi, ukusetyenziswa, iindlela zokulungiselela, kunye nolwazi lokhuseleko:
Iipropati: I-2-Ethylpyrazine lulwelo olungenambala ukuya kumthubi oluluthuthu olunevumba elimnandi elifana neleringi zebenzene. Iyanyibilika kuninzi lwezinyibilikisi zendalo kubushushu begumbi, kodwa phantse ayinyibiliki emanzini.
Ukusetyenziswa: I-2-Ethylpyrazine ingasetyenziselwa njenge-reagent kwaye iphakathi kwi-organic synthesis. Ingasetyenziselwa kwi-organic synthesis ukulungiselela iintlobo ezahlukeneyo zeekhompawundi, ezifana ne-pyrazoles, i-thiazoles, i-pyrazines, kunye ne-benzothiophenes. Inokusetyenziswa kwakhona njenge-ligand yezakhiwo zetsimbi kunye nokuhlanganiswa kwedayi.
Indlela yokulungiselela: Kukho iindlela ezimbini eziphambili zokulungiselela i-2-ethylpyrazine. Enye ilungiswe yi-reaction ye-methylpyrazine kunye ne-vinyl compounds. Enye ilungiselelwe ngokusabela kwe-2-bromoethane kunye nepyrazine.
Ulwazi lokhuseleko: I-2-ethylpyrazine ngokubanzi inetyhefu ephantsi phantsi kweemeko zokusetyenziswa eziqhelekileyo. Njengomxube wezinto eziphilayo, kusafuneka iphathwe ngononophelo. Xa udibana nolusu kunye namehlo, kufuneka ihlanjululwe ngamanzi amaninzi ngexesha. Ukuphefumla imiphunga yayo kufuneka kuphetshwe xa isetyenziswa ukuqinisekisa indawo yokusebenza enomoya kakuhle. Kufuneka kwakhona igcinwe kwindawo epholileyo, eyomileyo, epholileyo kwaye igweme ukudibanisa ne-oxidants, i-acids, kunye nee-agent zokunciphisa.
