Intshayelelo
I-2-ethoxy-3-isopropylpyrazine yi-organic compound.
Ikhompawundi inezi mpawu zilandelayo:
- Imbonakalo: Ulwelo olungenambala
- Ukunyibilika: Inyibilika kwi-ethanol, i-ether ne-benzene, ayinyibiliki emanzini
I-2-ethoxy-3-isopropylpyrazine inosetyenziso olukhethekileyo:
- Ingasetyenziswa njengesibulali zinambuzane kwicandelo lezolimo. Kukhuseleko lwezityalo, ingasetyenziswa ukulawula izitshabalalisi ezifana neplanthopper kumasimi awomileyo.
- Ikwasetyenziswa ngokuqhelekileyo kwi-organic synthesis njenge-catalyst kunye nephakathi.
Indlela yokulungiselela i-2-ethoxy-3-isopropylpyrazine inokufumaneka ngala manyathelo alandelayo:
1. I-2-Pyridylcarboxylic acid kunye ne-isopropyl bromide ziphendulwa phantsi kwe-catalysis yesiseko sokuvelisa i-2-isopropylpyridine.
2. I-2-Isopropylpyridine iphendulwa nge-ethanol phantsi kweemeko ze-acidic ukuvelisa i-2-ethoxy-3-isopropylpyrazine.
- Iyacaphukisa kwaye iyatshisa, kwaye kufuneka ihlanjululwe ngamanzi amaninzi ngokukhawuleza emva kokudibana nolusu kunye namehlo.
- Kufuneka kusetyenziswe izixhobo ezifanelekileyo zokuzikhusela ezifana neeglasi zokhuseleko, iiglavu kunye nempahla yokukhusela.
- Ngexesha lokugcinwa kunye nokuthutha, ukuphendula kunye ne-oxidants enamandla kunye ne-acids kufuneka kugwenywe, ukushisa okuphezulu kunye nokukhanya kwelanga kufuneka kugwenywe.
